Title: Dolmar 5000
Post by: dolmarfan on May 24, 2012, 02:48:20 am
Hello I am from Romania and  my wife just bought me a present a new dolmar 5000 DK made in 2008 .the chainsaw works fine after 6 tanks of fuel in it but after reading on some forums I have a question: Is the  factory carburateor settings corect or do I have to adjust?
Some guys said the carburateor is set to run lean.
At my dealer they said the settings are corect.
I dont have a cat mufller on the chainsaw.

I never considered the factory settings to be correct. I always readjust them myself

JMO unless you have a good dealer that sets the saw up for you. I have found factory settings to be way to lean or just not what I like in a tune.

For a work saw I like rich four stroking out of cut and then it cleans up while in the cut.

They may be lean in the states for EPA reasons but set correctly in Europe? Just a thought.

Thanks guys. I have  limitators on the H and L screw.The H and L screw at my chainsaw are opened at maximum.How to adjust them?

I turn the L screw 1/2 turn back from the factory settings.Is good or bad?

Dolmar is my first experience with a chainsaw!From what I read turning the L screw back t makes the mix richer wich is good?
Title: Re: Dolmar 5000

It is better to have it too rich than too lean

This one is set just right - can you hear the (4 stroke) flutter when he lets off a little in the cut?

Post by: Cut4fun . on May 25, 2012, 03:29:34 pm
Why was you adjusting L side?  Was saw having throttle response issues etc?  Where was your carb set up from factory H L without the stops?  Checked by ear or tach?

 If your rev limited stops are still intact you should be safe with the adjustments you are making. I hate to see you burn up a brand new saw fiddling if you dont know where you were at from the get go. 

I've seen stihl 290 310 390 with factory settings and stops in place be only a 1/4 turn out on H side and 2 or more on L side. This was checking after removing tabs and gently seating H L in while checking

Might be something in the service manual on your carb adjustments.

The sound is like the video posted by magnum660.
I have tuned the chainsaw by ear, I dont have a tach , and I have tuned the chainsaw without removing the limiter caps.The L screw back 1/2 a turn because I was afraid the mix was too lean.
Thanks for the manual Cut4fun2!

Post by: 660magnum on May 26, 2012, 10:13:22 am
In the video I posted, that is a big cut for a Dolmar 5000.

Notice the flutter sound in the beginning and end. That is what we refer to as four cycling.

It is desirable to be right at the break over point between smooth two cycling and the four cycle flutter for best power and longevity of your chainsaw.

While cutting wood, the engine should run smooth as in the video but if you lift the chainsaw slightly, the engine should flutter into four cycle.

Everyone is concerned here for with your model of chainsaw, the factory generally set them too lean.

Post by: 660magnum on May 26, 2012, 10:23:07 am
This next video is by a respected professional logger from Tennessee, USA (MDavlee)

It is a 5105 Dolmar chainsaw of the same family as yours and the high speed mixture is set correctly.

http://www.youtube.com/watch?v=I8NJknF-Gyw&feature=related

This next Dolmar 5000 is set too lean. There is some distortion in the video and you can hear some flutter but this flutter is the RM limiter in the ignition coil.

A saw is never set correct from factory regardless of brand, model, fuel or handler.

They all need to be set to perform best.
Each saw perform different. It can be a 10-20% difference in saws performance, that is pretty normal regardless of brand or model.
I notice a bit more variation in some models, but the Dolmar saws are very even when compared to other new saws out of box.

The 5000 saws were/are very good and are still made and sold. 5105 and 500 I sell here.
I have sold a couple here, none scored and all run Alcylate fuel (Aspen or similar).
I set the saws a tad rich and ask them to come back after about 10-15 tanks of fuel, I reset it after performance, not rpm or specs.

Plugs and fuel is important. Good stuff is well invested money.

Magnus I have a question: In Romania we have 95,98,99 octane gasoline.Wich one to use?
20 ml oil Dolmar for 1l gasoline is ok?
Title: Re: Dolmar 5000
Post by: Magnus on May 29, 2012, 12:34:50 pm
I would use 98 and a really good oil in excactly correct ratio.

I use a surringe to meassure and mix what I run in a day. I never store gas from pump. It lasts day's only here...

Post by: 660magnum on June 03, 2012, 11:44:08 am
I've seen them both ways.

.325" with a 8 pin sprocket

3/8" with a 7 pin sprocket

Personally, I like the 3/8" better

Post by: SawTroll on July 05, 2012, 09:05:11 am
There isn't the same need to set the carb lean from the factory in Europe as in the US (to comply with mindless EPA rules) - but I still totally agree with Magnus, that the factory setting never can be trusted.

Regardless of the market, it is the dealer responsibility that the carb is set right at the point of sale - but it is best to check yourself. The same setting will not be right in all conditions, there are lots of variables.

That usually happens on those saws (including my 5100S) - but it usually isn't really bad enough that I am worried.

I am keping my chain sharp but I think you are right about the dry wood. I have been cutting some dry oak!
About the set of the carb the dealer said the factory settings are ok!
I dont know a person wich I can trust to do a carb setting so.......
Thanks again!
Title: Re: Dolmar 5000
Post by: 660magnum on July 06, 2012, 11:48:09 am
I usually touch up the mixtures every time I start to do a little serious cutting.

My 5105 was very rich when I got it.

Learn to identify the "two stroke" - "Four stroke" point and use that as your reference setting?

The accepted measure is to adjust the chainsaw to run (when in the cut) just barely into the two stroke phase. If you lift up on the chainsaw slightly, the engine will four stroke. If you just rev up the chainsaw not in the wood, it will four stroke at the top end.

The problem with late model chainsaws is not to confuse the rev limiting ignition with four stroking!
Title: Re: Dolmar 5000
Post by: dolmarfan on July 06, 2012, 12:37:51 pm
I just got an email from dolmar germany and they said that the factory settings for europe are ok.
I listened again the dolmar5105 from the video the one with the corect carb setings and mine sound aproximativly the same.

That statement from Dolmar means OK for the coditions when setting them, it doesn't nesessarily mean they are right for your conditions! 

Carb setting is a continual prosess, far from a once and for all one!

Scored cilinder om my dolmar and Makita Romania refused waranty because the mixture  gas and oil was not corect they said to me today!
I use 20 ml  dolmar oil for 1 L gasoline!
Loks like magnus and sawtoll was right about the carb settings Makita Romania said they are ok again?
I have send an email to Dolmar Germany to see what shoul they say about the waranty!
I have a friend with the same problem with a sthill 231 and Stihl Romania sain the same things and I am sure that he respects properly the mixture oil and gas!
Is this hapening just in Romania?
My first chainsaw a chinese saw lasted 3 years and I was cutting with her 20 m3 of wood per year!

Post by: farmboy on July 11, 2012, 10:11:32 am
Sorry about the lean seize on your saw.  Good luck with your warranty.  Best thing I can suggest is buy a tachometer and tune by tach on this model.  Dolmar originally said tune to 14,500 max. rpm's.  After many scored pistons from lean seize they lowered the max recommended rpm's to 13,800.  Tune a little rich @ 13,500.

Title: Re: Dolmar 5000
Post by: 660magnum on July 11, 2012, 10:34:07 am
I think the poor reliability of the Dolmar 5000 piston/cylinder due to being set too lean from the factory and the resulting poor dealer/distributor warranty support has done more harm to Dolmar than all the good Dolmar/Makita ever did?

This is so wrong in so many ways.

 A good dealer should have set that saw up and then again when you took it back after break in for a retune.    JMO. Maybe I am just out of touch with the real world. But heck  I even do this for the people that get stuff from me.

Thanks in advance!

I left the chainsaw to idle for 20 minutes like the dealer daid after the repair the muffler had trases of smoke and oil and after 10 minutes of cutting is again shiny! I have repetead that for two times and everytime is the same! Is ok?

See if you can find any off the good ones listed in here. You might check with Amick's in links and ask for Tony to see about getting you one.  http://chainsawrepair.createaforum.com/ported-saws/chainsaw-tachometer-choices/msg10288/#new

Also I dont know if Scott at ChainsawR can get you one or not, just ask him, but he mails world wide.

Here is a video of a Dolmar 5105 with the high speed mixture set correctly for sawing the the size firewood he has on hand.

This is how your 5000 should sound when you are cutting.

If your engine sounds smooth the whole time, your high speed needle needs to be opened until it sounds like in the video with the fluttering.

Title: Re: Dolmar 5000
Post by: 660magnum on July 23, 2012, 09:18:30 am
Several things have to match.

The bare must be a small mount Husqvarna or Dolmar

The bar and chain must be of the same gauge. For example, .050", .058", or .063"

The sprocket on the chainsaw and the sprocket in the nose of the bar must be the same pitch as the chain. In your case .325"

These numbers may be written on your bar but in your case they may be in millimeters instead of inches.

I have noticed something interesting: IF I am cutting branches the muffler is black but after cutting a full tank of oak about 1 meter in diameter the muffler is getting white.The saw is tuned as rich as possible one more turn in the H makes no power!

Post by: Cut4fun on October 28, 2012, 10:06:45 am

In is leaning the saw out.   

Rich as it will go with limiter tabs still on H and L? You will need to trim the plastic tabs off to get full tuning of H 

Also out would make it richer and if no tabs were stopping you, you would be able to unscrew the needle out of carb.

are you sure your low isn't set to rich and the high too lean? and is it maybe bouncing off the rev limiter making it sound like it's rich?
Title: Re: Dolmar 5000
Post by: dolmarfan on October 29, 2012, 07:21:33 am
The limiter caps are off.
I am sure is 4 stroking because if I take half a turn out on the H needle the chainsaw has no power and is making a lot of smoke!
The L needle is tuned also a bit rich!

it will make a lot of smoke if it is hitting the limiter as your dumping unburned fuel into the hot muffler.

any time somebody complains about a saw that runs a little on the rich side while doing the small cutting, then the saw going lean while cutting bigger wood leads to either a tank vent issue or an air leak. could also be a fuel filter or inlet screen, but the saw is a little new for those issues to be poping up now. considering the saw has already ruined one piston, obviusly the problem wasn't fixed. i would take a look around the site here on how to do a pressure/vac test to either prove or disprove this. it's a fast easy test. why not take the time to do it?

What is the L needle setting? Is that two turns (or more) out as well? Is Idle strong and steady? Change in rpm as it change position? Hesitate on acceleration? Run strong in wood?

The 13 500rpms was without load and bar/chain mounted?
It is not that uncommon rpm as it hits limiter and can't go higher.

Pressure test is a good start. Test carb as well when you have the stuff out. Set carb under pressure so you see when needle open.
By adjusting the lever under pressure it gives more accurate amount of fuel.

The idle is strong and steady and was set also with a tach acording to the dolmar specifications!
In the wood no problem cuts like a maniac!
No change in rpm no mater the positon of the saw!
No hesitation in acceleration!
13500 rpm with bar and chain mounted!
The settings were made at a dolmar service and the guy said that 13500rpm is ok!No air leak!
A turn out meens that I go from a point A and get to the same point A in one turn right? A stihl dealer said to me that a turn out is - You go from a point A and get to the same point A in two turns!
Sorry for my english.

around here 1 turn out means 1 full turn (360deg.) :-\ some saws will idle perfectly fine, rev perfectly fine and seemingly run fine in the cut. what you need to do is make a long cut, and when your about to finish that long cut pull the saw out and right away check to see if it sounds like the saw is reving higher or sounding 'peaky'. unless you do a pressure/vac test, you can't rule out an airleak, just because the saw seems ok.

It is running a tad lean! Hitting limiter. She will want a bit more fuel. As you turn it out you will hear a difference in tone as she "four stroke" instead of hit limiter. There is more "clinging" in the rev limiter sound.

I doubt you have a air leak, but it is always the first step to rule this out so you know and not think..
Title: Re: Dolmar 5000
Post by: farmboy on November 12, 2012, 01:00:21 pm
Shouldn't be lean @ 13,500 unless you are on the limiter.  I have run mine @ 14,200.  Coil may be the problem or you have a vac leak.

I went one 1/2 turn out and now is 4 stroking but I dont now the revs because the service is 100 km from me.
So the diference betwen the hiting the limiter and 4 stroking is 1/2 turn.
Thanks guys!

The 5000's I sold here all had 13500rpm limit in coil.
If you swap coil out to another you get more, but not with coil it is delivered with.

I changed out a couple to 14 500 limit coil that was in 4600 and others...

What should I do- 13500 but no 4 stroking
                            -a little rich 12500 and 4 stroking
Title: Re: Dolmar 5000
Post by: Magnus on November 14, 2012, 04:32:11 am
I set them a tad rich. If you set it by ear to hear when it four strokes it can be different rpm's.
If you can't hear it, 12 000 is better than 13 500. To me numbers mean less than performance.

Most important is that it runs clean under load, NO hesitation going up in rpm and a strong steady idle.

If you do cuts mostly in firewood pile for example the saw lie on work rpm 75% of the time.
This is between 9 000-11 000 something depending on saw and settings.
This is the rpm you want to have high as firewood cutter.
Wrong settings stress the saw, create unneeded ware, consume time, waste fuel and prevent saw to perform correctly. Setting it lean will not make it use less gas / pile of wood, quite opposite actually.

Focus on top rpm is for limbing small spruce etc. The focus of high rpm is more than focus of how the saw perform.
You can take 3 saws, they all want different settings to perform its best. How they perform can be a tad different too.

Some firewood cutters here I set up 5000 saw with 3/8 chisel 15". Saw last longer, hold rpm up better and it is more fun to cut.

Title: Re: Dolmar 5000
Post by: Magnus on November 14, 2012, 02:54:04 pm
Not necessarily, four stroking is a sound the saw makes at a unspecified number of rpm, it is not certainly 12000 but more likely than 13 500.
I don't set saws by tach, I set them after performance.
Title: Re: Dolmar 5000
Post by: Cut4fun . on November 14, 2012, 04:28:20 pm
I like to set saws on the rich side and you can hear them clear up when they get in the wood and start cutting.  Like a blubbering sound out of the wood aka 4 stroking and clear up and sound like a mad hornet in the cut.  No certain rpm just by ear.

 I  use a tach to check saws settings with and make sure my ears are not way off and get one set to lean when I am pushing the limits looking for the quickest cut times (when goofing around testing stuff).  If you do like above I dont think you could ever go wrong.

WAG one is the stihl dino oil in orange bottle and maybe the other is semi synthetic or  synthetic smokeless or low smoke.  ???

AFTER 3 OR 4 thanks of fuel is normal for a saw to go lean when the chain is no longer sharp?At full wott the rpm is set at 12500.
Title: Re: Dolmar 5000

Settings of saw has nothing to do with sharpness.

If it is dull, sharpen it. Don't run blunt chains, they don't work right.

I'm not familiar with the Dolmar 5000 but have a Dolmar 5105 with a 5100 muffler. I would hae to assume the 5000 muffler is like that of the 5100?

I got a Husqvarna 288 exhaust deflector and made a hole in the side of the muffler and mounted the deflector over the hole with sheet metal screws.

But I have brazed extra steel tube tube outlets in them.

I don't find anything different with 500, 5000, 5100, 5105. All use [181 174 102] It could be different in USA, but I get the same numbers to order for all here.

Is that possible?

Just a idea for you. Get a Paypal account which will be connected to your bank and it will allow you to buy using your bank account anywhere. Plus it does the exchange rate of different monies used.

Here is some suggestions on tach choices.  http://chainsawrepair.createaforum.com/ported-saws/chainsaw-tachometer-choices/msg2778/#msg2778

Finally I got a cheap chinese tach around 40$ here.Not the best refresh rate but works.
Tuned idle around 2600rpm, 12500 rpm with no load.In the cut was around 8800-9200rpm. ;D

After the rebuild tuned by dolmar dealer was 13000rpm.
Tuned by me after I learnd from you guys about 4 stroking and 2 stroke in the cut was about 11500rpm and in the cut was about 8000-8300 rpm!

Title: Re: Dolmar 5000
Post by: Magnus on June 11, 2013, 04:02:24 pm
It is the performance in wood that is most important I think. Optimal RPM's is different on each saw. Setting after a specific top rpm is often misleading and can be a disadvantage.
If it holds 9000 in wood and perform correct I think it sounds pretty good.
Title: Re: Dolmar 5000
Post by: dolmarfan on June 12, 2013, 03:50:50 am
The sound is good in wood at around 9000 rpm in wood and according to the factory the saw makes maximum power.At full trothel makes a little burbel and is around 12500rpm. :)

At 12500rpm  tach, and the chainsaw works fine.
The sound at 13500 - dont like it.

It has a rpm limiter in the coil that is set at 13500 rpm. When it goes into coil limitation the tachometer will go nuts.

i've seen some that like to start cutting in at well below the '13500' they're rated for. the 5105 i bought new was cutting the spark at 12600 no load. most i've seen are around 13000ish flat.
i've also encountered a few that go well above the stated limit. same part number, very close to same build dates and want to rev well into the 14's, when they were supposed to top at the newer 13500.
i was lucky that weagant farm supply had an older 5100 unlimited coil sitting on the shelf me. still, anything over 13700 is getting lean on mine. some i've only been able to tune them to just barely over 13000 to where they sound maxed out.

I know there are several coils for this series.  Don't know about unlimited but the red coil came on the 14,500 rpm version.  It may be unlimited.  I know there is a red, white and I think brown IIRC.
Maybe somebody will post a list of PN's, colors, rpm's.
