Your 600 CFM Holley likely has an electric choke. They work good, but, one drawback of electric chokes is they cool and reset faster than the engine cools. After sitting an hour or two the choke might be closed again, then plus some pumping of the throttle causes the engine to flood. One other possibility is when sitting for an hour or two with a hot engine, the fuel in the carb bowls heats up, percolates and drips into the motor through the circuits inside the carb, thus, flooding the motor. One of those thick heat insulating gaskets or a phenolic carb spacer will usually stop that from occurring. The latter situation is more common when aluminum intakes are installed and the heat crossover passage is not blocked. Another much less common cause of flooding with Holley carbs when the motor sits is leaking metering block gaskets in the carburetor.

Your accelerator pump diaphragm may be dried up or needs adjusting if there is free[play in it.

Prob needs some adjusting, both carbs are less than a year old.

I’m having a similar issue with both my 82 and 70 with the Holley 600. Next time after it been sitting remove the air cleaner, hand throttle and see if the squirters are squirting. Once I engage the pump lever further, it’s begins to squirt. Fires right up after that. I believe it’s the gas these days

The only wires on my AAW setup that go from the steering column connector to the DD box are for the left and right turn signals. These are AAW wires 14A,B (Lt Blue) and 15A, B (dark Blue) 14A, B hooks to the Ford column wire that is Green with a White Stripe 15A, B hooks to the Ford column wire that is White with a Blue Stripe 14A goes to DD box #31 (my number) 15A goes to DD box #30 (my number)

I would forget what the mechanic said and check the timing and carb yourself. A mechanic is rarely a tuner.

yup, that was about 18 years ago but I drove it to work everyday year round and I don't recall ever having a problem with it.
