Whatdunnit

I picked up a husky 350 parts saw to get running, I had a spare 346 pc kit I ended up putting on it but I was considering just putting a new piston and ring on it if the cylinder is salvageable. (Meteor/ cabor) the old cylinder is clean with the exception of a little scoring below the intake. The piston is bar- coded bad on the intake side and pock marked/ melted on top. Curious if the cylinder is any good and what caused the major malfunction. Straight gassed? Also the felt filter was pretty plugged up.

Thanks

Check the bearings over real close. Something let loss in there.

I didn’t check the bearings over real well. The bottom looked so clean. And than I read the post where the guy sells the 372 and the new owner had problems (great thread) and it got me thinking and concerned a little. Maybe we’ll rip it back apart to play it safe. I’m a little concerned that the cylinder bolts might be a little long also. How about the marks below the intake, I can feel it slightly.

It looks like detonation on the top of the piston and dirt getting past the air filter would cause the skirt damage. It might have had bad fuel run through it to cause the detonation

Good call ozhoo and thank you! Took it back apart and the clutch side bearing race was toast. Still wondering about the original cylinder though, I would prefer to reuse it if it’s ok.the ring is always above the two marks below the intake. I can feel them slightly with my fingernail though.
