Crash and Burn
Where are all the Univents? Somebody should gift me with one, so they can be well represented.:biggrinbounce2:
..... The 44 has a 346OEP/C. ......
I wonder how that works, as the stroke is different between those saws? :msp_confused:

Yep, as you know Niko. I think its about .5mm if I remember correctly. The OE346 piston is the same 42mm bore, crown is just a little thicker. Machine about .050 off the crown, use a base gasket and you end up with .020 squish. Port timings is exactly the same.
Saw wasn't straight gassed either. The intake gasket failed and was sucking air. Found a picture of the cylinder
Beautiful eh?
ave you discovered that it has no chain on it? :msp_biggrin:

Hey, Niko: How DO you know this stuff?? Specs aren't my thing. I certainly don't have your facility with the stroke on the saws I run. I just run'em! First off, I lied about it being a new cylinder. It's the stock cylinder Komatsuvarna cleaned up after it'd been straight gassed. Anyway, we just got this one from him, so he could fill you in on the details. The way I understand it, he machined down an early 346 piston, and finagled a Caber ring onto it, so I guess that makes up the difference. That's about as much as I know about it. It runs great and the price was right, so I won't lose any sleep over it either way.
How ya doin'?? Good to let this stuff keep your mind off the hip!!

Stellar! Thanks for jumping in there and bailin' me out. I hate gettin' my information third hand!
You ain't Kiddin'. And to run it is even better! How did you clean it up? Acid, Drano, or honeing; or both? Whatever you did I'd like to learn your tecnique!Yep, as you know Niko.

Did not realize it was open port. Interesting.
