Do you think the manifold is the problem?
Had carb problem with my H. Cleaned and put in carb kit. Ran compression check and cylinders seem to be equal. Problem is that as the tractor gets warm it does no seem to be getting the correct mixture of air and gas and loses power after warm. Also I cannot get the carb to adjust rich on full rpm when adjusting the needle valve. Also the plugs show black carbon not as if it is lean. I am stumped because when it is warm after working it hard it wants to die and does not want to start until after it cools down. It also misses intermittently when being worked. I am about to change to a new manifold thinking that there may be a crack allowing exhaust gases to be mixed in with the intake side. What do you think?
