Hard Starting Hot

[Rich72C10]

This morning, my hard start came back with the Carburetor. She would turn over, get up to Fast Idle and die. This cycle continued about 5 times.

Luckily I bought a little check valve and had it on standby. It plugs into the inlet of the filter of the Quadrajet. Though it does restrict fuel flow but hopefully that isn't a issue for a stock-ish truck engine.

Though my understand is this should have correct any flow back: "removed the clip on the needle/seat to let it set when fuel is not flowing to prevent backflow". I that the case, then the check valve will not make a difference when I start her up tomorrow morning. So that begs the question, where is the fuel going (if that is actually the problem, no fuel in the bowl).
