Title: Husqvarna 2100 2101 1100 298
Post by: winland on July 11, 2014, 12:35:00 pm
Put a "new to me" 42" b/c on my 2100 the other day and went to kick some stump butt.
Luckily I also took along my 394xp, because it ended up doing all the work.

The 2100 starts easy, idles fine, runs good at WOT.  I cut into the stump about 6"- 8" and then it started to bog down.
Tried feathering the throttle, but could not find a spot that it would stay running.
I have not used the 2100 since last year on another big stump and work fine as I recall.

It had been run dry last season and put away.
Put brand new gas/oil in that morning.
Felt like it was starving for air or gas or something while in the cut.

What are possible causes?

So the last time it was tuned it was cold? And you were running in warmer weather, did you check the tune?

The 2100 has a governed carb and must be tuning while under load.  So they might sound fine when rev'ed up with no load because all the fuel is coming from the limiter circuit.  Once in the cut and pulled below the limiter circuit RPM it could be running very lean. 

As well, the limiter circuit could be the problem.  Their spring check valve often gets weak and dumps extra fuel at too low of RPM.  The limiter circuit can be disabled by placing an aluminum disk (cut from pop can) under the check valve (the brass screw plug on the right side of the carb next to the choke shaft).

Also it could be a fuel delivery problem.  Plugged fuel filter, crracked fuel line or the carb could need a rebuild.

Good luck!

Thanks guys,
I will put a smaller bar/chain on it do some test cuts and adjust the H side of the carb.
If that does not help, I will check and clean the governor/limiter screw.
Then rebuild the carb and replace fuel lines and filter.
Hopefully I can get it working without doing more damage.  ;D

I was unable to get good results with just re-tuning the carb.
Took the carb out and checked the governor.
Looks like someone had already defeated the limiter.
Found a small metal plate under the brass screw.

Will order a rebuild kit for the carb and see if that helps.

I have rebuilt the carb, but it had NO positive effect.
I have ordered a cheap pressure/vacuum tester to check the carb.
Hope to get that Thursday or Friday.
I took off the muffler to see if it was restricting the exhaust.
The muffler looked pretty empty except for the spark arrestor and it was clean.
Took a photo of the piston and rings.
Looks pretty good to me.

Post by: 660magnum on July 23, 2014, 08:27:53 pm
I have a saw that the piston looks brand new with all the machining marks on the exhaust side. To look down the boot it looks smooth on the intake side.

I got ready to put rings in it.

When I pulled the cylinder off, sure enough, the intake side was smooth as a baby's butt but there were no machining marks left. I decided to put a piston in it also for a long term repair. Nothing like leaking around the intake port and spitting back through the carburetor.

I have rebuilt the carb and did a pressure test on it.
It holds an 8 PSI pressure with no problem.

Looks like I am going to need our leader take a look at this saw and do his "redneck" magic on it.

That looks to me to be a crack in the cylinder inside the intake part? The crack appears to go all the way to the piston?

I was talking to Kevin on the phone and he had been thinking it was the intake block?

What do you guys think?
Title: Re: 2100 no power in the cut
Post by: KilliansRedLeo on July 24, 2014, 10:09:30 pm
I think you may very well be right Jim. I saw the crack but did not realize the what we are looking at is the cylinder not the intake block.

Title: Re: 2100 no power in the cut
Post by: aclarke on July 25, 2014, 12:35:26 am
 Appears to be a small crack/inclusion at the 7 o-clock position as well.  What's the history on the saw?  Does this model have an outboard carb support?
Title: Re: 2100 no power in the cut
Post by: KilliansRedLeo on July 25, 2014, 06:51:03 am
From what I can tell the carb spacer is NLA. Perhaps the crack can be sealed in some way. But it will definitely contribute to an air leak. Maybe a little JB thinned down somehow and forced into the crack?

The spot a 7 o-clock looks to be discoloration.  I cannot fell anything with my finger tip or fingernail.
I have owned the saw for almost 2 years.  I run it just a couple times last summer no problems until now.
It does have an outboard carb support.

Here are a couple pictures just to show the orientation of the parts.
It appears to me that the only place that unwanted air could possibly enter the cylinder via this crack would be at the very top edge.
Would a small, strategically placed, drop of super glue fix this potential leak?


Title: Re: 2100 no power in the cut
Post by: 660magnum on July 25, 2014, 11:32:29 am
That insulator block is made of a polypropylene type plastic or what we old timers call white nylon. Super glue with not actually stick to it or have any solvent reaction with the plastic but it may possibly fill the void?

Post by: Cut4fun . on July 30, 2014, 07:11:53 pm
I just spent 2hrs with this 2100. First tested and seen what owner was talking about. Start making cut and it would shut off. Tried it a couple times same thing.

Took it to the bench and pulled carb and tore it down checking things. I adjusted the fulcrum and the needle look new so put it back.  You replaced the needle right? Diaphragms looked good on both sides, so no use opening that new kit IMO.  The choke wasnt closing all the way but that is another story. Fixed.

Checked spark with the new tool and even after stops and testing it showed. GREEN (flashing) Proper voltage, ingnition is OK

I made  4 full cuts in 17.5" dry maple no problems and starting on 5th cut when raised up out of wood to hit 5th cookie she went into a run on like on the race saws. I hit the kill switch and it did nothing. So I then took my hand and pushed into the green weenie filter to block off air to shut her down.

While still hot I started trying to start and check things and it was just erratic with it's idle and starting when hot.

I am thinking there are bigger issues here from a  air leak once warmed up.  What do you all think, seals, base,  etc?

I dont know 2100's so hoping you all can shed some light. 
 
Title: Re: 2100 no power in the cut

I wish I could give you a definitive answer, but I can't the air leak is a good possibility though.
Title: Re: 2100 no power in the cut
Post by: Cut4fun . on July 30, 2014, 09:31:28 pm
The way it acted once warmed up made me think seals. 

When cold had perfect idle and blipping up to rpm. Walked to back to make test cuts and after it got hot after 4th cookie is when it acted up.

Also noticed someone at one time drilled a much larger hole in the carb cover over metering diaphragm. The oem one is still there too off to  the side.

Something weird I noticed is this cylinder is black. Dont look painted?

Kev, are you saying the metering side carb cover is drilled? Kinda odd, but if that's the case, that would tend to mess with the carb mixture somewhat.  I.e stihl Intelicarb system.  Doubt that's the real issue but it may make the carb adjustment fussy.  Make sure the enrichment system us indeed defeated, short of that maybe case gasket or seals are bad.  Loose cylinder bolts??   Adam

I did replace the needle when I rebuilt the carb, along with the spring and diaphragms and gaskets.

Never had the shut off switch not work.

Switch probably does still work. I would guess it was due to the run on happening when it was hot. Had it happen racing before too. Went to hit kill switch and saw just kept on going. Have to either choke them off or flood them with squirt bottle.

I'll know for sure when I try it cold again to see.  Pretty sure I remember using the switch other times too.
Title: Re: 2100 no power in the cut
Post by: aclarke on July 31, 2014, 09:47:15 am
Kevin.  One more thing I thought of that would give erratic carburetion would be a bent fork on the metering needle /fulcrum.  The forks are often bent from the mfg.  Take a close look at that.   
Title: Re: 2100 no power in the cut
Post by: Cut4fun . on July 31, 2014, 09:58:39 am
I pulled the fulcrum etc and looked it over before I adjusted it, nothing bent.

One thing I did notice. It is using a pinned attached metering diaphragm.  I had read in service manual there was the pinned and not in 2100 HS?
 I remember one of my saws years ago had troubles with pinned attached diaphragm. Went to unpinned not attached dia, fulcrum style and worked.

winland do you remember what type of metering diaphragm came out of the carb  or have a pic? Just a grasping at straws deal here.
Title: Re: 2100 no power in the cut
Post by: winland on July 31, 2014, 10:08:49 am
This is a photo of the original diaphragm that I replaced.

Also I found this youtube video.  Sounds a lot like the problem I am having with the 2100.

Only thing this dont use rubber boot. Solid intake block and I made sure all was tight. But didnt check the intake block you put on cylinder before bringing it.  I'll spray around it next start up and see there too then.

I also noticed your 2100 does seem to get leaner in the cuts yesterday.

Just so you know it had plenty of power in the 4 cuts yesterday till it went haywire on the 5th one.

Same dia so rules that idea out.
Title: Re: 2100 no power in the cut
Post by: aclarke on July 31, 2014, 11:00:15 am
Be worth a try running a non - captivated fulcrum on the carb.  You can cut the little ring that the lever engages off the diaphragm a polish the tab so it doesn't bind.

Me and this 2100 is going to fight. I tell ya that right now. LOL  4th freaking pull the recoil rope let go.  All 2' of it.  I put 3' of super strong recoil rope back in it.

Cylinder bolts checked out and was thinking maybe gasket between cylinder block was missing. So I pulled all of that to make sure and back together.

Then starting tearing back into carb.  Adam I did find bent fork on 1 side of the needle.  Instead of straightening that one. I just pulled everything out of the carb except the welch plug.  Knowing it was working right with that one. Noticed the new check valve diaphragm material was a little different.  More the of rubber style I like then material style like in it.   

Sprayed carb cleaner through all the holes making sure everything was working and not blocked anywhere. All checked out.

3 pull on choke she popped. 1 pull after she is running idling PHO.  Now to test and see what happens.  Hopefully the run on yesterday was due to the bent fork around needle and not seals. 

The on/off switch works.

I'm not sure if you said you checked this but did you check the tank vent? That jred 490 I have had a bad vent and it would lose power in the cut.
Title: Re: 2100 no power in the cut
Post by: Cut4fun . on July 31, 2014, 05:19:58 pm
I thought of tank vent today too Thanks Ron.

I made 8 good cuts with 16" bar buried. Then went wanky. Like surging through cuts. Air leak in my mind. 

Did some testing with carb cleaner like winland showed in mweba video and found  air leak between intake block and carb around carb gasket.

I think I have her figured out now.  After comparing the **** intake block winland pulled off and new gaskets that come in kit.  ;)

Title: Re: 2100 no power in the cut
Post by: Cut4fun . on July 31, 2014, 07:09:44 pm
 All day with this thing. But I think I won after this last test session after pulling a gasket off of one of my HS carbs and using instead of the supplied gasket in the kit that is wrong wrong wrong.  You cant see it when putting all together lining intake bolts up.

Noticed this thing is a GAS HOG.   But power to spare. I ran his fuel out yesterday, ran a tank of my mix yesterday-today and start on another tank of my mix this evening.

Then I noticed the 2100 laughing at me. I thought what the heck I'm going to :-\ :-X. The bar nuts were vibrating off and 1 was already in the weeds. Got out the magnet on rollers and located it.  Yep were going to fight if it stays around.  :D :D

Just got done testing it out today. Perrrrrect IMO.  Got the tune set to 4 stroking and clears up nice under load in the cut.  Just like I like.

You know when I pulled your plug that was in it in the beginning and switched one of my plugs in it, your plug looked lean to me. Stands to reason now that we know it had a air leak.

Yes, they are suppose to be specific to the 2100 and a few others.
I was hoping they would come with short bolts.
Have to go to ACE hardware to get some.

winland are these block off plates specific for the 2100?    Pretty slick, never seen the husky oem block off plates up close. 


Yes, they are suppose to be specific to the 2100 and a few others.
I was hoping they would come with short bolts.
Have to go to ACE hardware to get some.



Whats stuff like that cost if you dont mind sharing?

Kevin find the part # for the Husky tool you're interested in (found in the list below, and in the 2100 WS manual), and then search for that part # on any of the online Husqvarna parts sites.

All day with this thing. But I think I won after this last test session after pulling a gasket off of one of my HS carbs and using instead of the supplied gasket in the kit that is wrong wrong wrong.  You cant see it when putting all together lining intake bolts up.

Noticed this thing is a GAS HOG.   But power to spare. I ran his fuel out yesterday, ran a tank of my mix yesterday-today and start on another tank of my mix this evening.

Then I noticed the 2100 laughing at me. I thought what the heck I'm going to :-\ :-X. The bar nuts were vibrating off and 1 was already in the weeds. Got out the magnet on rollers and located it.  Yep were going to fight if it stays around.  :D :D

I like how the hole is cut in the air filter cover rather than remove the cover. Just looks better IMO. Good job figuring out the issues Kevin.

A couple of photos of the actual problem that Kevin found was causing most if not all my problems.
The gasket that is supplied in the rebuild kit is not "oval" enough to cover.

Here's the correct gasket.  I use these on old Homelites, Poulans, and Husqvarnas that run Tillotson HS carbs, as the RK-23HS supplied gasket doesn't have enough 'meat' around the impulse passage.

In a 4 stroke, the lower one would be the wiper ring, correct?

Lots of 2-stroke engines have 2 rings.  I have some very old saws ('40s, 50's, and early 60's) that have 3 rings.  They're all compression rings, as there's no need for oil control rings on a 2-stroke of course.

Ring drag is considered a parasitic lose on engines .One the other hand mutliple ringed pistons last almost forever as does the entire engine .

As an example some of the old John Deere and Caterpilar engines had 4 compression rings and two oil rings .They are still running after 50 60 70 years on the same rings .Not too fast or powerfull  just run forever .Old rock solid Evenrude and Johnson outboard boat motors are the same .About the only way to kill one is to straight gas it .

Not real worried about the rings or circlips as will go oem and caber there.
Anyone run either?

 Needing 2 for cylinders I have to remove transfer for a guy. Went ahead and ordered the AO24057 ball hone to finish the crosshatching with once they are cleaned up first.

Both cylinders cleaned up.  Guy in group has used the  Episan with caber rings with good results.

Went to order 2  Episan and none in stock.   

Was offered 1 on the chainsaw repair group when a guy bought 2 over 2 years ago. So I ended up going with 1  Episan  and caber rings.
Found one 2100 thin ring piston and have a new set of 2100 thin rings coming too from another guy.

This was the lightest scored one, not that bad but on both sides. The other one had heavy aluminum transferred on ext.

Have the thin ring piston soaking in Berrymans B12 right now to try and clean more carbon I feel might still be in the grooves

I learned something yesterday. Being I only usually work on 2100 2101 etc one at a time. I never noticed some of the cylinders used different threads and bolts for muffler.
#2 was a PITA yesterday trying to find the right parts out of the boxes and fasteners. Still shorts some fasteners.
#3 will need some parts ordered and bunch of fasteners. Looks like he is going to bite the bullet and buy new coils being good used has never turned up.
Said he was out cutting with the #1 I did before these yesterday = thin ring saw.

#1 oem thin ring
#2 new espian piston with cabers
#3 oem piston thick

Someone had cut the case on the one 2100. So it isnt getting built. Saving topend and crank for others.

Last one to be built from the box of parts. Finished it around 9pm last night.
Used coil came from a newer member on chainsaw repair group fb that I hooked owner up with.
I think that makes 10 runners in these for him now.

This is one has the espian piston with caber rings in it to see how they do.  Had good psi from get go starting last night.

 Do have a question. This full wrap was the thicker newer grey. The other full wrap was black grip and guessing older one. Which ones go to which?
This saw is 2101 tag and another one is 2100 tag. So going to do some cover swaps for him after 4th. The last 2100 to come in has 2101 covers. This 2101 got 2100 clutch cover.

One before this last one I put a black handle full wrap on too.  One before.   

There is another one right now with the last black handle on it 2100 with 2101 covers.   I like the feel of the thicker grey ones myself. He likes the black ones.

Saving a pic of the velocity stack Scarr makes for these.

I thought they had been anodized but he said made from nylon 6/6

That thicker grey handlebar may well be an aftermarket part.  A few outfits in the PNW made them.

If it's OEM Husky, then it was likely sold on a late 2101XP.  Those were made during the time that 268/272XP and 281/288XP saws were sold with that thicker grey.

It said 2101 on recoil but could be 2101, never looked at tag. But it had the 2100 pro safety full wrap.  Built super strong and thick grip. Thicker then the grey full wrap grips I tried on them oem and way thicker then the black covered ones.

OK you husqvarna 2100 2100 1100 298 etc etc buffs.   Had 2 more in yesterday.
The question = One had a tank that had a lip and channel where the front handle bolted to it. Never seen this on all the rest so far. What did the tank come on if not a 2100 2101.

Still one of the best loved saws Husky ever built. It was very well designed and extremely strong,and the long stroke and full 100cc made it a real brute and it would happily pull any length of bar. Being a heavier sturdier design than modern saws they could be rebuilt again and again, they also had the torque to be happy on any Alaskan sawmill too.
I'm sure many people still have fond memories of running them. A few years ago I was in a shop and opened an old cupboard to see a really black oily neglected one sitting inside,I asked the owner what he was keeping it for,he said "It's an old piece of junk,I'm throwing it out",so I rescued it and took it home. When I washed it down it looked hardly used and it had the sturdy "West Coast" handlebars on it. The internals looked new so I tuned and modded it and it ran great,sold it in one day for $600.
What a lot of people don't know about the 2100 is that the oiler is designed so you can double the oil flow for a long bar,you simply remove the oiler and move a screw pin from hole 1 to hole 11(2),marked on the oiler.
It still is the king of torque of any 100cc saw made since.

When our shop sold chain we charged "per driver" for the length of the chain,for some reason .404 was the same price per driver(or close) as 3/8",so a lotta guys with long bars used the .404" because there was many less drivers in the chain so it cost less.
The saws are brutes and will happily pull .404 chain,with long bars many prefer skiptooth which makes filing faster,especially with a long bar.
To plug the governers in them we simply dropped in a welch plug from leftover carb kit parts,works fine.

That part about the two position oiler I didn't know about the 2100 . I run a 32" bar on my 2100 and it always oiled okay so I never delved into it .Good info to know .

I put a 42" bar on my 2100 for milling.   No extra oiler because the oiler on the saw really put it out.   
Title: Re: 2100 no power in the cut
Post by: Midpines on September 09, 2019, 02:40:53 am
All day with this thing. But I think I won after this last test session after pulling a gasket off of one of my HS carbs and using instead of the supplied gasket in the kit that is wrong wrong wrong.  You cant see it when putting all together lining intake bolts up.

Noticed this thing is a GAS HOG.   But power to spare. I ran his fuel out yesterday, ran a tank of my mix yesterday-today and start on another tank of my mix this evening.

Then I noticed the 2100 laughing at me. I thought what the heck I'm going to :-\ :-X. The bar nuts were vibrating off and 1 was already in the weeds. Got out the magnet on rollers and located it.  Yep were going to fight if it stays around.  :D :D

THANKS!


This is the post which lead me to find the final solution.  I wonder if it was the same wrong gasket supplied in both kits.  My saw is my dad's old Poulan 245 which has never ran well enough to use as a saw since it came from the factory.  It was the impulse passage, a rerouting channel which at the other end from the hole though the gasket, which was left slightly uncovered and leaking.  I found the old gasket and used it as a pattern to make a new one. 

The saga I read here have a lot of similarity with what I've experienced with this saw.  I had one of those run away events like you described.  I just buried the chain in wood and that stopped it. 

I've also plugged the governor thing.  Those run away events is what I think those so called governors are supposed to limit, but do not stop.  What I think they do is vent gasses into the diaphragm chamber lifting it away pulling the fuel valve closed.  And I think when that happened it bends the inlet control arm.  The aim I think is to prevent the saw from coming apart, perhaps starting a fire. 

There doesn't seem to be any literature about them I can find.  Just mentions here and there that they exist, "and to be sure to plug them with a disk you have to make."  Every where I read that.   I used that grey sealant, just a bit on the tip and then screwed it back in. 

The saw I'm working on has run away a couple of times in the past as well.  That was what caused my dad to box it and never mess with it again.  I found the control arm bent out above the bottom of the diaphragm chamber by 30 thousands. I think that is also why those diaphragms have that keeper in the fork at the end of the arm so that when the so called governor vents gasses into the diaphragm chamber it can pull on that arm really jamming the fuel valve tightly closed.

I built one for a guy using espian (might be spelled wrong). Since no meteor offered. My next choice was going to be vec.
