its always seems to have a tune issue, and the H fuel screw never seems to make it diesel ???

Carb could be dirty inside or stiff diaphragms. Tune the L screw to "4 stroke" before you tune the H screw. Also, an air leak around carb, base gasket, crank seals can cause saw never able to tune in.

Ran a compression test on the saw? I've had a hard time tuning them if they aren't within spec on compression. Anything less than 90psi and you'll likely need new ring(s).

If you have the high speed more than 2 turns out you have major issues. Looks for an air leak as others have said.

One thing...I find hearing protection helps me to hear a saw "4 stroke" easier, especially the small saws.

My 350 was giving me problems keeping tune and no power in the cut. Found low compression, 105 psi. Installed an aftermarket 346 top end and the saws never been better.

Sounds like an air leak as someone else said. This series of saw has that crappy intake boot clamp made of plastic. (until the updated metal one came out) I've seen a lot of them toasted because of it. also where the carb mates to the intake boot leaks especially if someone has tightened the carb bolts too tight. And the bearing cup where it mates the plastic case. Thats where I'd check for your problem if your carb diaphragms are good.

I'm guessing a air leak like stated before , check bottom of the carb boot , they Crack there often. I would also clean carb . I wouldn't recommend running it in this condition.

Rebuild the carb, and check the fuel line... and if it has the plastic intake clamp, that may be an issue, as well.

I was thinking about the 346xp/353 saws. Not sure how much they have in common with the 345.
