Long story short, I have a 2009 372xpw saw, 28" bar. Got it used with low hours. Around 2016 or 2017... Wasn't used much but sits a lot. (Inside a truck) Leaking bar oil, piston is scored on exhaust side, still have 150 psi compression though. Saw got hot and siezed up when it cooled down, wouldn't turn over. Sprayed some Liquid Wrench in the cylinder and it freed up right away, turns over real easy now. Did compression check after it freed up. Pulled the muffler and some scoring I can feel with a bamboo skewer.
Looking at a rebuild with Meteor 50mm or just pull it apart and sandpaper it smooth again?
I'll need some gaskets, and do a pressure test first, have not tried to fire it up again.
It got clogged up in the chain sprocket from noodling in big douglas fir rounds, really green and wet wood in PNW. (Issaquah WA) I unclogged it, cut some more and then it died again. Put saw away, would still pull over when it was hot. When I went to work on it the next day it was froze up. After I freed it up and did a compression test (150psi) I noticed it was leaking bar oil. Never leaked before.
I called the parts guy at Wolf Creek saws in CO and he thought the Meteor 50mm piston would work on this saw, and to check my crankcase gasket as well.
I can try to find an 75cc OEM piston and cylinder, but am leaning towards the 50mm Meteor kit and replacing the lower end bearings and gaskets, (or new Crank OEM if I can find one...) Basically a new saw.
Perhaps I should try to fire it up again at some point? Not sure what to do here, or if I messed it up.
Gas had been sitting for awhile, and was using Lucas Semi Synthetic 2 stroke oil with Ethanol free 92 Octane fuel. (From a multi-fuel pump, not a single fuel gas station pump) Always has ran great in the past.
Thanks and I'll check back in awhile, I haven't ordered any parts yet but my exhaust gasket is broke so I can't run it until I replace it, and check for an air leak, etc...
Great discussions here, just sort of picking people's brains for some direction to go. OEM on this saw maybe for crank, but I'm not sold on the 75cc EPA cylinder porting as compared to the original 50mm 71cc design. I just cut firewood once or twice a year and load into my truck with a liftgate/Tommy lift. These were huge rounds and was trying to cut them down first. Cut great until I started ripping the rounds...
