Piston ported spitback.

[67L36Driver]

I have a high mileage 038 here with a good deal of carb spitback.

Time for a new piston?

Saw runs and cuts fine.

If it runs and cuts well it is fine. Some spitback is normal.

SOME spit back is normal....if the saw is soaking your hand from spit back it's time for a new piston as the bottom of the skirt is worn down and not sealing properly. Not gonna hurt anything, just might run funny. I'd run it until she's tired and then do a piston, rings, and reseal.

Actually I'm more worried about piston skirt failure. It do make a mess when it happens.

It probably has some wear marks on the intake side of the skirt but it sounds like it's ok for a few dozen more cords of wood. You might pop the cylinder off and eyeball the skirts.

If he pops the cylinder off he may as well replace the piston and rings. lol AND maybe do some mods!

038 does have a strong rep for self preservation!

That series is probably one of the toughest ever made especially the mag .

Paid $250 for the lot.
Ordered new OEM clutch springs, clutch would grab the drum at 2,000 rpm. Bar rails need some love and some of the chains are near junk.
Pulls hard.
