    Well, got the carb for my brothers truck a few days ago, and when we put it on, it stalls once you shift into gear. So I play with the idle, but the only way to stop the stalling is to crank it so high it diesels after shutdown. So I guessing fuel mixture is the next thing to play with? Is that right? Or is there another culpret I need to look for.

    btw, this is on an 85 C10, CA emissions, V6 262 engine, 700r4 trans. Carb got new mixture sensor, TPS, and master choke diaphram during the rebuild, and we were told that everything was readjusted to factory specs

    any help is greatly appreciated

    Are you absolutely sure there is no vacuum leaks at the base gasket,or hoses,intake gaskets??.Sounds like what you are describing,try spraying carb cleaner around the base gasket and other suspected hoses and see if it makes the motor stall out,(dont spray the distributor cap or plug wires!)if it dies out during that test,you have a vacuum leak.If the carb has an idle stop solenoid that isnt working that can make it stall too,also an EGR valve sticking open can snuff the motor out at idle too--might not even be the carbs fault--Good luck! /forums/images/graemlins/crazy.gif
