Re: Hard Starting Hot

The stock ACDelco is right at 12psi.

With it idling, and warmed up good .. kinda peek down into the fuel bowls and see if its dripping gas down into the intake on idle. Then, shut it off. Check again .. I'd bet you'll have a slight drip. That would indicate the fuel pressure issue as the culprit. Too much pressure will impact the needle and seat combo in the carb and allow it to keep dripping raw gas.
