Could this be part of the problem? The trunion and cam plate aren't centered.
aagitch, I will try the other valves I have to see if that helps, if it does then I will know what I need to do.
I've had this tractor for a while now but just haven't taken the time to get it back in shape. Can't decide if to sell it or keep it, I really want an 1872.
