Hey guys,
I just got the 390 back in my '68 F-250 last weekend and got it running. Now whenever I slam on the gas from a stop she dies. I installed a pertronix kit, new plugs, wires, cap and rotor. Set the timing 6 degrees BTDC. She runs great on the open road. Once moving I can slam on it and she taked of like a mad man. Any ideas? The carb is a reman with around 2,000 miles on it. It did this before I did all of the upgrades but not quite as bad. Any help is appreciated.

Thanks,
Corbin

What kind of carb. When my truck is hot, with a Holley 4v, and I start it after a hot soak it will smoke and stink of gas but what is worse the next attempt to give it gas will kill the engine. After that it is fine.

Its an autolite 2100 2bbl. It idles great. I can give it all the gas I want and snap the throttle and it doesn't die. When I power brake it she stumbles a bit and usually dies when I try and break the tires loose.

Replace the Accel pump on the bottom front of the carb or adjust the lever closer to the body of the carb.

I wondered what happened. Thanks for putting it back up Keith, you da man! Anyway, its a reman carb so the accelerator pump should be good I will, however, try moving the linkage in to the next notch on the accelerator pump and see what that does. Just curious, why would moving the linkage like that help the stalling? I'm trying to learn as much about carburetors as possible because the automotive program I am in doesn't teach us about carbs.

Thanks again for your help.

Changing the lever closer to the body of the carb for the Accel changes how much / fast it gives the accelerator shot of gas...
I would also try bumping your timing up to between 8-10 deg and see if that helps. 6 deg is pretty low for todays fuels...

To bad they don't cover Carburetors in your class. to old school these days I guess...
