So I have some bad news. Was out testing it this weekend. Changed the mains to 220 and it seemed to run much better. Unfortunately, a bit of the porcelain part of the spark plug broke off and seized the motor up. Full pinned in 5th. Locked up. Just stopped running. Got it to free up after kicking it for a bit. (Shouldn’t have done that in hindsight) piston and dome are like very rough sandpaper. And the cylinder doesn’t look too hot either. Any ideas. Sorry about the poor quality. They won’t let me upload anything over 53k
