I've fixed alot in the 9n but it's running rough when at high throttle idle. Sounds like when you are going down a steep hill and the engine is holding you back. When I put the plow in the ground and work it it sounds great. After a lot of work it does get rough and will start to backfire some. Not a lot but I know something isn't right. New wiring harness, new plugs and points. Everything is gapped to spec. What else can it be? I've checked the carb, I have great fuel flow with fresh gas, the tractor to sat for about 2 years. Does the carb need rebuilt? Thanks as always. PS the seals aren't leaking anymore to those that followed that saga.
