Hi guys, I've been battling an air leak between carb and intake and what I think is blow-by so I got a bunch of carbon buildup on my piston head. When I disassembled to clean the piston head off, I decided to take a look at the cylinder to make sure everything was ok. Looks like a small ding in the wall, previous owner said it had soft seized before.
How bad is this and what is the best way to take care of this: re-hone, new ring and the works? Will I need a new piston?
