As Joey already noted, the odd cover was used on some SP60 and SP80 saws, the one on e-bay now is actually a 10-10 (600001) according to the tag. I bought another saw from him earlier, had it listed as a D-44 but was in fact a 1-76. I haven't done anything with it yet but seems to have very good compression, according to the stamp on the bottom it has been bored 0.030 over. He offered me that saw for $50 + shipping but I didn't get back to him about it yet so now he has it listed. If it should happen not to sell in this listing, I'll take it up with him on the side.
Nick - I have 6 or 7 different IPL's for 250's including the one Cliff mentioned with the illustration of the Super 250 on the front cover (long, black cover with air holes) but inside the part numbers are all the same for the block (62481) and all show thick rings. If you have an IPL with different information, I would love to have a copy.
I have a late model 250 with the short black air filter cover and black clutch cover and round muffler. It has decent compression but I have not made time to do anything further with it. If I can find it, I will have to pull the muffler to see if it has the thin rings as well.
The 48691 part number is correct for the thin rings in 2.125" bore use in the 1-81HD, 1-72, 1-75 and 1-82, 1-85. My 1-85 really rips, if you have a thin ring version of a standard 250 I would really like to hear how it runs next to a standard 250 with thick rings. What is the block number listed with the thin ring version of the 250?
