Feels like it has good compression but if I pull it slow I can almost hear some leaking out of the carb .

Finally got a chance to watch your video , your right Bou. The intake valve was fine but the exhaust valve isn't sitting in the seat right, or the seat has worked it's way up . Valve has like .022 of lash

I've got the head off, looks like the exhaust valve isn't sitting in the seat all the way . Pulled the valve and cleaned the carbon off of it with emery cloth and lapped the valve in . Got the valve lash better but still looks like the exhaust valve isn't seating right
