I ran my MC16 up yesterday, got it up to temperature. I had a bit of an exhaust leak on the front cylinder, so I took the pipe off to give it a clean and I decided to have a look up the exhaust port. I spotted these 4 marks on the piston skirt. (see pic)
I did a bit of research and it says that it's the start of a 4 point seizure, due to lean mixture. Would that be due to the exhaust leak?
If anyone has any ideas or comments, I'd like to know.
Cheers
