New carb starts then dies after 5 seconds

[joeybtl]

I recently got a new Edelbrock 1406 for my 84 Chevy c 10 and put it in hooked everything up and started it I pumped the gas and it finally started but would stop and die after 2-3 seconds any help?

What is the fuel pressure? Is the choke plate closing? Vacuum leak?

 

[joeybtl]

Idk the fuel pressure. It’s a electric choke it’s open about a penny wide and I can’t seem to find any vacuum leaks

Make sure your idle mixture screws are out about 1.5 turns each, not run all the way in.

With the engine off, cycle the throttle linkage a couple times. You should see a constant stream of gas out the accelerator pump nozzles.

If no gas is coming out the squirter, pull the fuel line, put it in a container, and crank the engine to make sure your fuel pump is working.

Can you keep.it running by pumping the gas pedal?

Random thoughts.

I’ll try that when I get home. I can keep the engine running as long as I’m on the pedal yes
