leaking holley 3310. hard restart

Where did you set initial timing?

That is the one thing that will kill you. It may not have enough, throttle blades open too far and activating the transition/main circuit at idle. Your situation is one of those symptoms.

If it doesn't start at basically the flick of your key, it's not set correctly. Cranks over a bunch and won't fire or you need to give it pedal to start, needs more initial timing.
