At least you can save the block! 😀 Pistons are a lot easier to find and replace. The ridge you had on the cylinder wall would have been aluminum transferred over from the piston. Some guys use muriatic acid to remove it as the acid will quickly destroy the aluminum without harming the cast iron cylinder.
The guy that owned this six horse motor missed one needle bearing and dropped it in the motor while putting it back together. He got about three minutes of run time out of it before he realised something wasn’t right.
