I have a 69 with a edelbrock750 carb. Lately the car has been shutting down while driviing and hard to restart. Last night on the way to a show it died . It would restart than died and restart and die. I finally had to get a flatbed to bring me home. Talk about embrassing.
I have checked the fuel filter and cranked the engine with the fuel line unattached to clean out the line. Plenty of pressure. What should i check next. I'm going to clean out line from tank to fuel pump. Don't know much about carbs. Any help and step my step procedure on checking floats would be appreciated. Thanks, Tom

I can start the car and it will run for about two minutes at idle and reved up and then it stops. When i get out and move the throttle i can see and hear the gas squirting so i thinking its not in the fuel line. When i restart the car i need to push the pedal to the ground . I'm thinking the problem is in the carb.

Tough one to troubleshoot remotely.
I'm not a Holley guru either.
A couple other thoughts:
- If you had a coil, or ignition module breaking down due to heat, it could act the same way. Some electrical issues can be very temerature specific. Don't just assume it's the carb. Make sure you still have fire when it dies.

- If it is a fuel starvation problem, it would help if you had a fuel pressure gauge in the line at or near the carb so you could tell if you still had pressure to the carb. They are cheap and easy to rig into the line. Might want to put one in, even temporarily so you can eliminate fuel pump or pick-up issues. It might not tell you what was happening when it quit, but it'll help you know what's going on when you try to restart. I'm not one for shotgunning when I can get actual data without a lot of cost or work. I found a fuel problem once by putting one of those Mr. Gasket clear filters in the line near the carb and saw bubbles in the filter when the engine was reved. Had good pressure at idle but there was a pinhole in the rubber line near the tank. Didn't leak fuel on the ground but when the engine needed fuel, the pump sucked air into the line thru that hole. Starved the carb when running down the road.

Point being that unless one of these folks who are 750 experts knows the answer, you need to eliminate the simple stuff first. Or, if you have access to one, swap the carb out just for a test. That's another easy way to isolate the problem.
