I have a stihl 044 that has lost compression. I took the muffler off and can see the piston is in bad shape. I plan on re building the top end. Can anyone tell me if this has a 10 or 12mm wrist pin based on the serial number in the attached pic?

Measure the wrist pin or can you post a clear pic of the pull start side of the saw by the oil cap and muffler?
 
12mm Saw....You have some work to do finding the cause of that melt down!
Thank you, it was caused by lending it to a friend who put the wrong gas in it. Needless to say, I dont let anyone borrow my saws anymore!
 
I know this is a little old, and it's in the wrong area, but yeah. I'll affirm that's a 12mm. Changeover was in the 129 serial number range.

Definitely figure out what caused it. Of course there's the straight gas possibility, or operator error in trying to shake out the last few drops of fuel at the end of the tank. If it wasn't a known operator error, then my money is on crank seals on a saw that old.

Thanks for the reply. It was a gas issue for sure. I actually just got the parts and rebuilt it today successfully. I just sunk it into a couple logs outback and its cutting like new. For now anyways!
