Car starts then dies

Working on a 1973 Baracuda with a 340. After changing carb, fuel pump & filter new plugs and wires the car starts and then dies unless I sit there with foot on gas...

Sure sounds like a bad vacuum leak. Was the carb new or used? What have you done to tune it?

remanufactured q-jet (tomco) I have adjusted metering rods but no rpm change when doing so. I checked all vacuum lines and found no leaks, had to use carb spacer adapter to mount carb. I can put a edelbrock on and it runs smooth but I need edel for my camaro.

Have someone squirt WD40 around the base of the carb, and other possible leak paths while the engine is idling. If rpm goes up, there is a vacuum peak.

When i had that problem i just adjusted the fast idle screw under the choke. Just pull it all the way to full throttle and it will expose the fast idle screw. Then turn it clockwise to set it up higher. Good Luck!!!!

Just my opinion here, but I wouldn't trust a Tomco carb or kit any farther than I can toss it.

Hey I was wondering if you guys could tell me if a truck drives for like a few minutes and then dies. But in an hour you can run it again. I was thinking it was the fuel filter or the ignition. The truck is an 89 ford f-150 with a 460. thanks guys, the input from

That sounds like a bad fuel pump.. The gas is what keeps the fuel pump cool and when the fuel pump heats up it might give out... But i would try the filter first...

In any fuel delivery dilemma, uncork the carb line and crank away into a gas can. Sometimes the pickup socks in the tanks get junk in them, causing a real hard problem to diagnose.
