I just got an early 036 and it has mahle cylinder part number 1125 020 1206. Apparently there were two different cylinders offered mine without the compression release that may have desirable porting and this part number 1125 020 1206, the listing on ebay says kolben. Could I use either part number if I ever need a p&c? The piston is scored below the rings on the skirt, there was no aluminum transfer to the cylinder or scoring and no scoring on or above the rings. The pic looks worse than it is. I don't know if I should change the piston or just run it? I deleted the base gasket, opened up the muffler and port matched the exhaust before I even ran it. Compression was 165 after the delete. I don't know if it matters how many pulls it took to get it there though?
I just bought the items I was missing so I can learn how to port by practicing on this cylinder or a junk one and a pressure tester adapter. I'd imagine I can find numbers to go with on here that are tried and true. The only porting thread I read so far had someone widening their exhaust port. Strange thing is I measured mine and mine was already as wide as the number they were trying to achieve by porting. I thought someone ported my saw, but you can tell it's untouched. I've only ever opened up transfers and an exhaust port on an xpw cylinder so i've got a lot to learn. I will read the book(s) everyone suggests.
I still can't believe the bearing on the PTO side is shielded on this saw. I never expected to see this and wouldn't have believed it had I not seen it.
