Well, all I can tell you is that It was running well, running fast, then stopped. The motor still had a lot of pinch in it. I still have the piston /sleeve/connecting rod which is still attached to the piston. The piston was freed by pushing down on it but, the sleeve would not come out of the block. The only thing I think I replaced on this motor was the bearing. Funny, I was wondering what to do with the motor parts.

I tried everything short of dynamite and c4 to get it out.

I tried asking a friend with a GRP puller to get it out. No such luck.

Heating to 300 degrees to slightly expand the block in order to get the sleeve out. Nothing.

I tried hitting the bottom of the sleeve with a screw driver to get it to hopefully free it up so I could pull it out from the top. No such luck.

Finally, it took me over 1.5 hours to slowly mill the sleeve out without damaging the block.

I purchased a new kit to rebuild the block and upon trying to put the sleeve in, it would not fit. I didn't want to force the sleeve in as I have never had to do so with any other engine.

The head doesn't even have a scratch on it. I try to take really good care of my engines and I really like Rossi engines at that. I have a Black magic and a Rossi LSK. Sleeves were a little tight on these engines, but, not like this.

Anyway. That all I have on this one.
