Run it, cut it, or trash it?

[Freak007]

I picked up a pile of "junk" saws the other day that I am sorting through to see what is repairable, and what is parts. One of them is a Jonsered 2166 (Husky 365xt) that was a former tree service saw. It had a rod bearing failure which sent parts into the cylinder, damaging both the piston and cylinder

I am of the "when in doubt trash it" thought, as I don't like spending time and money to repair something twice... That said, I do think the walls will clean up and this cylinder could be salvaged by cutting the squish band and base...

Or am I wrong?

Assuming I am not; I know many people do a gasket delete on a 372. I prefer to run a gasket of some kind as it makes future repairs infinitely easier. Removing adhesive from an assembled crankcase sucks. Do these cylinders have enough meat at the base to cut (hypothetically) .040 to bring the squish back after the band is cut? How much can be reasonably cut from the band before compression gets out of control?

I don't have a lathe, but I am hoping I can find someone to cut it for me if that is the route I decide...

I think the damage around this port, with the cracking in the plating would be my biggest concern. I believe that is one of the strato ports, being the upper one?

I didn't notice that when it was in my hand, but I did see it when I reviewed the pictures. I will definitely look at it closer. If both crank and cylinder are trash, then it's likely headed for the parts pile.

Also in the pile is a 2165 (365XP) that has a (non-critical) cracked crankcase, and missing other parts... I was hoping the crank was good to use in this saw, but if not I might still be able to make one from the two...

I tend to try and make something from nothing frequently. If the crank feels good, slap something together and see what happens

I bought a Tecomec 365 cylinder kit for cheaper than it would cost to have the cylinder machined. They run great and there would be no chance of a failure from damage.
