Over the weekend I picked up an 044 project, used and dirty but not abused. It's an early 10mm, with the metal tags and red switch shaft. When I pulled the shroud off, I was surprised to see the top fins going straight across the cylinder instead of the usual near-45-degree angle. I initially suspected it was an aftermarket item that somebody threw on there, but it's got the Stihl logo. Compounding the strangeness, there are no other logos or names that I recognize -- no KS stamp, no raised lettering that says Mahle or Gilardoni.
It's definitely a 10mm wrist-pin saw. The ring-positioning pins line up neatly between the intake and transfers, which I wouldn't expect if it were a 12mm cylinder paired with a 10mm piston, but my experience with these doesn't run very deep. It has the D-shaped combustion chamber. If this is not the original cylinder, which is plausible because it did seem a little cleaner than the rest of the saw, then I'd say the replacement was done years ago. At some point the saw ingested a small screw, which got pinched between the piston and the edge of the combustion chamber a few times before it was expelled. Thankfully it didn't touch the plating or do any other meaningful damage.
So, uh... has anyone seen one of these before?
