Have a 66 with the 289 and auto lite 2100. The problem I am having is she has a stumble on accel I with push the gas and she takes off for a second then stumbles then it catches it self and takes off. I have replaced plugs wires cap rotor coil points condenser fuel pump fuel filter sending unit and rebuilt the carb. And the battery is new I am at a loss

My truck would stumble as you went from idle jet to main jet when the accelerator pump seal was shot. The spray in the throat compensates for the fuel need and jet transition.

The accel pump was replaced in the rebuild it has done this since I have owned her. It looks and sounds like the pump is shooting enough fuel into the carb. Float bowl was set 3/4 deep as per spec. Vacuum leak I am not sure of sealed the carb to spacer and spacer to body mount. Replaced the dizzy advance to carb hose. Where is the other vacuum? It has very little in the effect of hoses in the engine bay thank god.

Oh ya I rebuilt it because it sat since 95 and had orange jello in the fuel bowl which I am guessing was once gasoline. New accel pump new power valve new pcv valve haven't replaced that hose yet
