my 6hp isn't taking a really long time to start or not starting all off a sudden but ran find the last time after i finally got it started. compression test is only reading around 12 psi and doing a leak down at TDC you can hear air leaking out prop and the piston rings....checked the valve clearance and they were a litle too wide of a gap. Therefore, I adjusted them to the middle off the specs. I'm guessing that the valves are either really dirty or stuck...rings could also be stuck...pulled intake off and there was a lot of carbon on back of intake valve.
Question is...how can I go about trying to clean the piston, rings, and valves with seafoam without running the engine....is there anyway to tell if the exhaust valve is stuck without taking it all apart./???
Note that everything else was checked and is good such as fuel delivery and spark and choke operation
