I have miner skuffs on my cylinder walls was wondering if this is normal you if you look in from the exuast side they are on the back of the motor compression is 139 pto 137 mag. Please help.
Actually pretty normal to see some markings on the cylinder and piston. Full synthetic oils allow more scuffing than the standard petroleum. One of the downfalls.
I haven't had very many posts on this topic. So I'm still kind of worried the more I think about it. So please post if you think I should look into this further. Thanks for your help. G-P
