The issue has been there for about 6 months. In that 6 months i replaced the original fuel pump with a Facet electric fuel pump specifically designed for the psi of this carb. About 4.5 psi. I replace fuel filter. I replaced coil and points ( which im about to install the electric ignitor just for the hexk of it ). The carb is only 2 to 2 1/2 years old. Replaced all new fuel lines as well. Fuel is getting to carb at 4.5 psi no problem using guage to watch. Under 40mph truck runs perfect. No roughness. Idles like a humming bird. I had to learn this engine on my own and pretty much worked on nearly all engine components. From 40 to 45 mph i can push on gas pedal all i want and its like im not pushing on pedal. Once it hits 40mph i have gas pedal effect back with zero issues if i keep under 40mph. I thought the governor only kept me from pushing throttle beyond certain point not letting me get up to 45mph for like 30 seconds and then unloading. Also if im going like 43mph for a min and slightly take me foot off pedal, it kicks in the dead pedal effect again until im back down to 40mph. Again, thanks a million. Im losing hair scratching my head on this.
