The Stovebolt Site Forums The Parking Lot '60-'66 Trucks 1966 C10 stalls

I own a 1966 C10 with a 327 that will stall when I accelerate too quickly, either from a stop or while driving down the road.
If I accelerate very, very slowly it runs fine.
Could this be a carb or timing issue?

Being a boater water in the carb bowl comes to mind.

I would not have thought of that danman.

Have you checked your fuel filter?

Accelerator pump. With the motor shut off look into the carb as you stroke the throttle and you should see a big shot of fuel discharged out of the pump orifice. If not it's carb time.Accelerator pump check ball plugged.
What kind of carb??

I had the same problem with my 66' and it was the fuel pump. But I would also check the fuel filter.

Another thing to check is the strainer on the end of the fuel sender pickup tube. If there is sediment in the tank, during acceleration, the fuel agitates and the debris can temporarily clog or inhibit fuel flow through the tube.

Sounds like your running out of gas so to speak. Not necessarily a fuel pressure problem but a fuel quanity issue. Any one of the above could be it but a paper fuel filter will swell if any water is introduced into the fuel system and slow down fuel delivery. A bad fuel pump will have enough pressure sometimes, but won't be able to deliver much in the way of quanity. Carb float level too low and the bowl will run out of gas on acceleration. Just my two cents worth but I'd check your fuel filters first, the in-line one and the one in the fuel connection point on the carb, if so equipt.
