Doug,

if you have to ask you should take it to a professional however I will try
to explain.

Remember a 2-cycle engine relies on the fuel mixture to cool the engine, a
lean engine will run fast but can overheat an seize easily.

Make sure to hold or clamp the saw securely.

Turn the low and high speed adjustment screws out 1 1/2 turns adjust the
idle screw , then slowly turn the low speed adjustment in until the engine
starts speeding up then open it back out a little until it slows back down a
little, now adjust the idle for preferred idle speed ( chain should not be
turning)

Run saw up to wide open and turn in the high speed adjustment until the saw
runs at full speed then turn it back out a little so the engine sputters a
little DO NOT run it wide open for more than a few seconds.

To verify the low speed you should be able to pull the throttle in all the
way and it should not die, if it tries to die open the low speed slightly
and re-adjust idle if necessary.

If the saw only has one adjustment screw, skip the low speed setting.

I've got a Micro XXV saw that I can tune well enough to run, but can't
seem to find the right tuning, with no hesitation or stalling. Does
anyone have carb adjustment procedures fo these engines?

I'm new to this site and Ken's answer was right on and I thank you,I got the saw running smoothly again and working my butt off using it. I'm from Michigan in the States. This seems like a great site!
