engine stall

[Anonymous]

I just got everything finally ready to drive and when I do the engine stalls and cuts off whenever the give it a good bit of gas in gear. It runs fine in park and responds quick and never bogs down. If im in gear, I can slowly give it gas and it will run ok, but whenever I try to accelerate at a higher rpm thats when it starts to cough, sputter, and even shut off. I have a dual advance and I don't think It's hooked up right, and a new 2 barrel holley. Does it sound like a vacuum leak or something else?

I had a problem like that the other day. I'd left the handbrake on.

8) sounds like you are not getting enough fuel through the accelerator pump, or the pump shot is too fine. try a larger pump shooter IE; go from say a 29 to a 31.

I would first double check all the ignition realted stuff--ie. timing static and advaceing (is timing advanceing when reved?) -firing order(sometimes a crossed plug wire will run great without load). cap , rotor, These are all more easily checked than things like float level -jetting-etc.
If you don't have a timing light-get one you need it. Once the ignition system is eliminated then move onto fuel.
My first suspect would be timing malfunction --either inial setting off --more likely not advancing properly.
Second suspect would be trash in carburator. You say 2bbl Holley, maybe a bit of trash clogging 1 of the jets. I recently had to take an autolite 2 bbl apart 3 times in 2 weeks for tiny specks of trash finding their way into the carb jets--not an uncommon thing especially if the fuel system has either set a while of has been worked on recently.
As i said, i like to check ign. system first as it is much easier to check as no dismantleing is needded for diagnosis.
