I am going to test how they came in. Then after carb adjustments and tune if needed and then test again after muffler mod on the ms390. Going to see if a 025 would need any muffler opening or not.
The 390 the guy says is a PITA to start and by 3rd pull rips the handle out of his hand on kick back. :D What is your take on that? I have ideas.
Oh and he said not to sharpen the chains that he does that himself. So when I get time next week I sure up it cuts to start off. Looks to have a 24" 25" stihl bar on it under the scabbard.
So what percentage do you think the 390 will gain in 1 cut time with same chain after muffler mod and carb adjustments? Compared to just carb adjustment and no muffler mod.
Not going to go by the way I will test when it just came in. Might run iffy who knows right now.
If his chain wont cut for chit I will put my chain on for testing.
I know what I got out of a MS290 with muffler mod and carb adjustments. I was really surprised by that one.

... 30 min caveman muffler mod ...
Care to clue in a newbie on what that means?
A cheap no cost muffler modification that takes 30 minutes with a drill, dremel and grinder. I only use all 3 because I have them on hand. I call them caveman muffler mods.

Does that 025 have the adjustable carb on it?
On shelf till after July 4th. Will let you know later on.
What did your 025 project have for carb?

I'd imagine though that a little work on the muffler would wake them up a tad .
Post by: Cut4fun . on July 01, 2011, 06:37:57 am
The non adjustable carb. I think it runs on the lean side now so i dont even want to take the spark screen out yet. That little bugger does impress me with the power it has. An adjustable carb will make it a keeper. ;)
I peeked at it this morning very quickly. The 025 has H and L on cover with 2 holes going back to carb. Cant tell if one is blocked off or not.

If it doesn't have one the fully adjustable carb is a WT215, about 35$ brand new.
MOS you see above and it seems to be on others too.
You can get a Walbro WT-215 carb from a 021/023/025 or MS210/250/230 and swap the throttle shaft and choke shaft from your carb into it and You'll have a fully adjustable Walbro carb. This setup is much better than the Zama junk on the 200t's IMO. The WT-215's can be had cheap if You watch ebay for 'em.

MOS this 025 has a H and L carb. After looking at the muffler on it, all I could see doing was opening the 3 exhaust outlets up. Otherwise it looked fine and was already louder then the stock MS390 muffler :D . Re-tuned the L H and idle and she runs great.
The 390 picked up a 1000 rpm after muffler mod without adjusting carb. Re-tuned L H idle and she runs good for what it is.
Sorry it was just to dang hot for making video's of before and after.
Looks like this. White spots are added in.
Post by: Cut4fun on July 14, 2011, 04:43:41 pm
The muffler itself was opened up big time compared to stock 2 slits it used to breath out of.
Also when was the de-comp put on the 390?
This one didnt have one and was a complaint of the owner. The new d ring took care of that with a carb tune.

I think though it seems that many manufactures are using decomps more so than was standard practice from previous years .
Post by: man of stihl on July 15, 2011, 02:44:14 pm
I can't recall ever seeing an actual 390, 039 yes .It didn't seem to have such excessive compression to even need a decomp .My guess is they are using cheaper plastic starter parts.

This guy is running .325 18". How do you think this saw would pull 16" 3/8.
Is there a clutch drum for rim set ups for this family of saws? I cant remember off hand.
Also he is thinking of having me open his muffler up. Which I know gains 20% to 23% right there.
Reason is he owns a DP 440 I did for him with 20" 3/8.
Post by: 660magnum on July 13, 2014, 06:31:37 pm
036, MS360 stuff will work
Be careful with old stuff as they changed the bearing size somewhere along the way. You may need to keep a specific bearing with a drum?
Post by: Cut4fun . on July 22, 2014, 12:56:32 pm
Guy bought it for $50 PHO not running on word it ran when put up years ago. Hopefully this dont get to interesting.
Looks like it could look like new with a wipe down. I can see the bar code sticker on the front of crankcase.
Anything different on the 029 super compared to the 290, know the same cc? Maybe tank vent etc updated?
I know about the 029 being smaller bore and super being same as 290 bore. New owner didnt.
Post by: Cut4fun on July 22, 2014, 05:43:12 pm
Off switch wasnt working and lucky had air filter off to close the choke to shut off. The plastic switch seems out of kilter or things are misaligned.
Pulling carb next for a look.
Missing prefilter too.
Anyone got good pics of the plastic switch at brass clip and trigger areas. IPL not helping me much looking at it.

The clip was under the assembly switch as shown in pic. This caused half throttle at start, choke not working properly and stop switch not work all due to that clip. :o The on/off I understand, but the half throttle I still dont see how it should effect that but it did.
Otherwise the saw checks out and is a great deal for the guy for $50.
9 chains done too. :-X :-\ :P

Chain and bar wasnt getting any oil. Pull bar off check yep oiling.
Check and cleaned bar groove and oil holes. Checked and cleaned bar mount even though new oil coming out. Modded oiler holes thinking they didnt line up just right on the after market forester bar. Added a extra oiler hole in bar on both sides.
I went through this about 4-5 different on off deals testing.
Any idea what I found to be the freaking problem as to why I wasnt getting oil to bar chain. :D

So I tried to to trim the end part of afm fuel line to shorten it to stop the kinking but it is just to weak in that spot and still kinks.
Guess it will be OEM line or my Redneck stihl fuel line method if this is how all the aftermarket stihl fuel lines are.

Unlike the oem that feels thicker walled.
I tried to shorten the end to take out the kink but nothing helped.
Also had a primer bulb fall apart on a husky 350 I installed it on. Just a bad day for aftermarket parts.
So I ran my redneck fuel line method and she runs like a charm now. Just have to reuse old tank grommet from original line.

Issues, no start and rattling.
I ask owner if he had a minute as I thought I knew what the rattle was. Got the muffler off and showed him how it was disintegrated inside. Also looks like something might have chipped :-X the top right edge of piston. Otherwise piston looks fine. Maybe been that way since new or he got lucky and it spit it right back out back into muffler. :-\
Order a muffler and see about the start issue later. Also needs a new 18" bar bad.
8) update: just got off phone and new b+c approved. Told him will order once it is running. OKed for the muffler mod treatment on the new muffler. :P
Post by: Cut4fun . on November 16, 2016, 07:26:56 pm
Plug was lose and gap was almost closed. Need to ask owner if he had plug out and dropped it checking things on his own. Then didnt put in all the way.
The chain was one of those ones you just shake your head at :o ::) . Had to be alot of vibrations to the saw.

Post by: Cut4fun . on November 18, 2016, 12:48:20 pm
Talked to owner. He never removed plug. So plug got loose and something closed that gap. I still think foreign material from inside the muffler that had ratteled apart got back into it. There is a small chip on the left side top of piston right if looking in. Plus today looking inside around the inside of sparkplug could see little tiny molten type balls. Looked closer and could see them on top of the piston too.

Muffler modded and tuned with new set up.
Never did figure out where those metal type very small beads came from. Just going to guess from inside the muffler. Cleaned up best I could and checked over and over and seemed to got it.
Also looks like some detonation on the piston above ring area and edge. Guessing running old mix.

Is there a clutch drum for rim set ups for this family of saws? I cant remember off hand.
Stihl sell the 290/390 here even with 18 or 20" 3/8 chains.
Rim sprocket kit #1125 007 1002 is 3/8 pitch, and the 290/390 shares it with the 360/340

Stihl 029 super and a 311 by another guy.

Also came in for leaking bar oil underneath. Line wasnt connected to the oiler anymore. Also noticed the bar chain was dry. Just figured this.
But the worm gear spring was broken off too.
Cleaned all the bar oil out tank and line and put on a new filter. SOG the freaking fuel line was squirting at the tank. So ended putting new line in it too.

Post by: HolmenTree on March 05, 2017, 09:52:56 pm
Took the stud out. About half the plastic cut in threads are pulled. Going to try the redneck fix first then the oversize if needed.I believe you have a stud threading into a plastic crankcase like a 019 I have with the same problem.
I have a pic of the oversize studs with part numbers in a thread here. More then just this series listed too.
Only way to fix it is push a metric bolt the same size as the stud in through the oil tank.
Now if you can't find a press in metric bolt with a toothed shoulder to prevent turning. You just need to weld 4 thin short beads around the shoulder and sharpen them up with a die grinder.
Tightening up the bar nut will seat it nice.

Guy on the chainsaw repair group just showed a redneck repair he is trying.
= Philip Ynot
2 hrs ago
Pretty simple repair. save me having to replace the whole tank assembly on a stihl ms290 the Oiler nipple broke off when I was disassembling. Picked up some small brass tubing from the hardware store reamed out the hole just to create a friction fit assembled and then used a little super glue to seal the plastic. Don't even know if I needed the glue the friction fit was very snug. I think you should work just fine.

Fixed the broken recoil and removed the boot lace used to try and fix part of that and broken handle.
Replaced a missing old school tank vent. Made it up.
Then it will just back fire. Soooooooo
Sheared fly key. Issue is the fly nut will loosen part way and then just spin. Never had to figure that one out. Can’t figure out out to remove the spinning stripped out fly nut. Ideas?
Can tight back but need to line fly up for timing.

Now if it holds. I cleaned both sides and was scared to go to tight. So hand tighten as good as I could just using 1/4” ratchet. Using orange loctite.
Crank thread were fubarred. Nut threads was gone. Just enough threads to tighten at lower area.
Thanks for the ideas yesterday. 😎👍

Just wish they were done without the inner cage. But I bypass them out the front. I just hate they always rattle apart.
