TH is correct, it's low enough on the cylinder that there isn't much heat there. The important fins are the ones around the exhaust and the fins near the top of the cylinder. Probably wouldn't hurt to get the block glass beaded to remove the rust, and then paint it, and most important, store it inside.
Broke the engine in my 112 :(
Well, I was cleaning up my engine and noticed there was rust buildup between the cooling fins, So I got a screwdriver and as it lightly touched the cooling fin it just fell off, then the next one fell of as well -_-. So unless there is a cheap way to fix this right, i guess i am looking for a new block.
