OK update. New fuel pump, new fuel valve and new filter. Machine still won't do anything except idle. Even drained tank again and refilled. I did hook up a vacuum gauge to the pulse line and I am getting a vacuum pulse of 5 inches. I have already taken carb apart and checked things but didn't have a compressor. So this time I will have a compressor near to blows jets and orfices out.

Just really has me stumped being it was running great. shut down to clean air filter and wouldn't run after that.

Pull apart and clean the main jet. Sounds like the pilot jet (controls idle) is ok, but the main jet is plugged.

Have you checked the fuel tank vent line for restrictions? Try running it with filler cap loose or off completely. If it runs better check the vent hose for mud, kinks or being melted shut by the engine/exhaust heat. Mine melted shut against the exhaust pipe and would stall under full acceleration. Buddy

I know the "VOICES" aren't real but they have some great ideas.
