I guess my TPS voltage is a little off. It reads about 0.6-0.7V at the lowest setting I can adjust the engine too (curb idle screw) without stalling. Ed mentioned that I need to turn that little torx screw with a special tool to set the TPS minimum voltage.

With that being said, is there anything else that can cause my engine to stumble when I accellerate? I have to flutter the peddle in order to keep from stalling if I go from a dead stop. It gets better as the carb warms up, but never completely goes away. It idles fine... only when I hit the gas (mildly or wildly).

So with the bigger cam, should I be thinking about switching to GM#7029922 for a lighter power piston spring? What about jet and rod sizes. I think I am getting enough gas off idle. In fact I may be getting too much. Is 0.074 too big?
