No problem. For right now, if you see any fuel dribbling out of the boosters while either idling, or when you shut the engine off, set the floats down a little extra lower for that side -- we can always fine-tune them at a later date. Then blow out your air bleeds, all eight of them, with carb cleaner and chase it with a blast of air from your compressor, say around 40psi or so. Have both idle mixture screws backed out about one and a quarter turns from seated, and then give us a driving report. Crap in the air bleeds is the absolute #1, no doubt about it, happens every day, cause of poor off-idle and low speed performance on your Holley.

i just can't resist that old joke, but how exactly do I "crap in the air bleeds"? Seems like that would be awkward. (Meltzer's rule: always go for the cheap joke!) s

Uh-huh. patrickt's rule: Always get the fee first.

I finally got around to actually replacing the little secret hidden set screw that Holley uses to control the opening of the secondaries on our 4160 carbs. I could adjust the existing set screw with a special right angle screwdriver, but it was a real PITA. So, I replaced it with a nice 10-32 cap screw with a spring and washer. On a big FE stuffed in to a Cobra, cracking the secondaries makes a huge difference. I know you're busy on other stuff, but I thought I'd post a pic of it for the benefit of anybody with a Holley who has idle problems when the engine gets nice and hot. Cracking open the secondaries is almost always the solution, and putting in an easily accessible cap screw, instead of monkeying with the hidden set screw, makes it quick and easy to adjust. Holley really should have built them this way to begin with.
