Holley dripping gas into barrel

Nothing to do with dripping fuel, but you need WAY more initial advance, and likely need to recurve the distributor

Causes of dripping....

High fuel pressure, dirt in needle and seat or other damage, incorrectly set float level, or "if a foam float" the float might be "water" logged.

It might also be "partly" at fault that you need so much throttle opening to keep it running (with that timing) that it is pulling fuel over the top so to speak. Still should not be dripping, tho
