Holley carb. gurus needed!

Fuel should not be dripping from the boosters. Either a float is stuck or the float level set too high. Also, does your carb have four corner idle adjustment? If so, set the idle screws for maximum vacuum at your desired curb idle setting.

Exactly! Floats are too high, or needle/seat is stuck open. You did kick up the fuel pressure too, but I seriously doubt that 6.5 PSI will blow past the needle valve, but if they're getting weak/old that could be your problem too.

Check float level first!

The problem seems to be fixed now. All I did was remove the secondary bowl again, checked for any debris and put it back on again. I don't know what was wrong....
I DID notice that the two front idle screws screws want to be turned ALL the way IN or it won't idle right. What does that mean?
FWIW, I only have two corner idle adjustment.
Other than that, it seems to run fine now but I don't think the idle screws should be all the way in like that......
