Engine will not stay running

460 4v … 73 t-bird… had carb. rebuilt,I put some primer fuel in carb. runs for about 1 minute, fuel pump is pushing fuel though the fuel line.

If the line pressure is good and it’ll run primed (meaning the spark is good) then it has GOT to the the carb. My guess is that the needle valve in the float bowl is not opening properly and allowing fuel to be pumped in. The float may need to be adjusted.

Um…I’m assuming you’ve already tried the idle adjustments?
