Message: <blockquote data-quote="kilohertz" data-source="post: 51556" data-attributes="member: 6974">Okay, well all new ignition high voltage side, timing correct, governor working fine, no improvement, so back to basics.I decided to recheck compression on the original problem cylinder (#2) and found it was down to 20PSI when hot, the rest are about 75 when hot. The engine was running fine with light load and I played around the yard moving some snow into a pile for my son to play in. It ran fine. So now I know why it boggs down easily, one cylinder is basically dead.So now.....I put a little ATF and MMO in the crank, same into the gas tank and ran it around for a little while then removed the pipe thread plug on the intake manifold and ran it at about 1500RPM then killed it with ATF into the intake. I will let it sit for a day or two and see if that does anything. The chambers were quite carboned and I pulled as much out with my fingers as I could, then blew out the chambers and put the valve cover back on when I got it running a few days back. So I know the valve is free but probably not seating properly. I put a tablespoon of oil in the cyclinder and rechecked with no improvement so I am going to assume the rings are still okay.Question, will I damage anything by running it like it is for a while to see if the valves find their happy place again? I am hoping not to have to pull the head and valves, but it's not a big deal if I need to. I would rather just see if it fixes itself. Remember, this unit crapped out 4 years ago and the guy let it sit outisde for 4 years so it may need some time so run in again.Your thoughts?CheersPaul</blockquote>
