stihl 290 310 390 029 039

Just got a stihl 390 and 025 in to work on. Both might be
getting a 30 min caveman muffler mod that sure beats the heck
out of paying a $100 to a ebay seller. :o
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.

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.

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. ;)

The 039's really were not bad saws ,enough power .However it nor
the 029 could hold up to professional use such as a tree service
company .Then again those boys aren't real gentle with them
.Actualy they beat them to death truth be known .
I'd imagine though that a little work on the muffler would wake
them up a tad .

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.

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.
