I found a good video for tuning the Poulan Craftsman chain saw carburator:
I ordered the splined carburator adjustment tool so that I can adjust the
non-adjustable California 'pins' for the Low and High settings.
It's important to note that we need 92 psi in order for a 2-stroke engine
to run according to the dealer I spoke with today so I'll also check the
compression (I need to change the fitting on my compression tester which
was for 70's model car spark plugs with a different thread than this chain
Anything else you suggest?
Follow the steps in the video -- that was good. He tuned it by ear. I
do this with all my small engines.
He suggested removing the muffler to check for scoring on the rings
and piston. Unless you have piston, rings, cylinder damage -- chances
are your compression is _good_. This is not an old unit.
Cross the state line into Nevada and adjust the carb, so you don't
break the law <G>.
I'm close to the Pacific ocean. I wonder how far I have to go out to be
governed my international law. :)
I can't wait for my "splined" tool to arrive. The "pins" on the L and H
carburator screws seem to be smooth but we'll see when the tool arrives.
It was a good suggestion to remove the muffler to check the rings; and the
92 PSI is a good idea to test compression also (although the Craftsman
chainsaw is only 1 year old with only a few hours on it).
I'm beginning to hate Craftsman / Poulan ... by the way ... but I'll save
the rant for another day.
The screws are recessed in a metal surrounding. It would be very
difficult to do. I did talk to a couple guys who said they used those
crimp-on wire connectors and slid them over. I tried that method but
couldn't get it to work. Maybe I was doing something wrong. Anyway, my
tool has paid for itself... $5.
Also on a side note to all that is following.........when dis-
assembling something as complicated as a carb, or even something you
have never taken apart, take pics of it BEFORE and DURING dis-
assembly. By doing this, you won't be confused as to where that spring
goes, where the linkage goes and etc. when you want to re-assemble it.
Thanks for all the help you guys. This is my followup message.
I never could get it started. I brought it to an engin-repair shop and they
just called to tell me it's unrepairable.
The compression was 50psi but apparently two-stroke engines need 90psi to
He said he removed the muffler and he could see the scored piston. I have
NO IDEA why the Craftsman/Poulan piston scored after only a year of
occasional use, as I have been the only use of the chainsaw and I never
Sears has a 2-year warranty but I'd have to find my receipt and they might
say I neglected it (even though I can't imagine how I did that).
Next time someone can't start a two-stroke, one of the first things I'll
ask him to do is check the compression and remove the muffler to see if the
pistons are scored.
PS: Any idea what to do with the now-useless chain saw?
I had a guy bring me his 14hp Kawasaki mower that didn't run. He took
it to the biggest small engine repair shop in Columbus Ohio. They told
him his cylinder was scored and had low compression. They disassembled
it and it was in pieces. Cost him $200. I looked and the cylinders
were in great shape. I lapped in the valves and gaped them. Started
I suggest you get another opinion since you only used it occasionally.
Many shops take in stuff and never even attempt to fix it, only to
charge you a "diagnostic charge". I hope they didn't charge you.

...I've never heard of a sheared key on a saw. Try a minute spray of carb c
leaner down the throat of the cab...to see if it will pop. If it pops, get
a carb rebuilding kit for it.
I suspect he's fighting an extremely lean condition . Kalifornistan has
them set the damn things so lean they'll barely run , the cure is to open up
the low and high speed needle valves a bit . The problem is that "they"
don't want you to do that , so they make the adjustment screws so you need a
special tool to adjust them . My solution (Ryobi weedeater) was to use my
dremel with a cutoff wheel to cut a slot for a regular screwdriver in the
head . Runs swell now ... but I still can't get the neighbor's Stihl to run
You say there is a spark, in the spark plug, or just from the wire going to the spark plug. Have you tried a new spark plug, they do crap out especially in 2-stroke engines which is what I believe you have in your saw.
