Holley vacuum secondary float stuck?

Is the float stuck open or closed ?

If open - its either out of adjustment float set too low, or the float has a pin hole in it and it sinks allowing the carb to flood. Or it could be excessive pressure (unlikely if using a stock mechanical fuel pump)

If its stuck closed, its from crud in the inlet valve, or the float is way out of adjustment way way too high.

Determine which is the cause, and correct it. Good luck.
