Hello, I have a 199? gt6000 that I got used. After fixing some switches atc it ran OK but always required choke to run well. I have changed the carb, and fuel pump ( I have another engine) and for the most part have been able to use the tractor. Now it runs for about 1/2 hour then quits. After cooling off for a few hours it starts right up. Today I re-routed the fuel line outside of the engine shroud thinking maybe it was vapor locking but still did the same thing. The fuel filter never seems to be full of fuel and I would think it would because it is lower than the inlet to the fuel pump. I am thinking about replacing the entire fuel line and filter again.
Any other ideas?
