I'm sure you could sleeve one and if done correctly it will have the same power .

I resleeved a 125 some time back with cast iron but it took me days not just hours .Had it not been a relatively rare model I'd not have spent the time .

Keep in mind on buying a cylinder or piston these things had three different bore grades a-b-c .You can't miss match them else you'll either have a sloppy fit or else you'll hang it up trying to stuff a grade c piston in a grade a bore etc .

Rambling on  one of McCullochs bright ideas which wasn't all that bright was using needle bearings on the out sides of the piston .If they fail which they do it will grenade the piston and more often than not "needle"the  block .Something to watch for on used parts .

Now just my opinion .You'd be better off biding your time until eventually one will come up with a bad ignition ,bad oiler or something rather than a pile of parts somebody had lying around in a 5 gallon bucket .Often you can buy the whole saw with a rough exterior but totally intact instead of buying basically a pig in a poke with a pile of parts for about the same price .You just take the best parts out of two and make one which is exactly what I did on the 805 .

Fact being I only had slightly more in price than what they try to get just for an OEM  piston without even a set of rings and usually a grade b or c .That wouldn't do a person a bit of good unless you had the block to go with it ,just more parts to go in your own 5 gallon bucket .
