Holley float levels?
Posted: Sat Apr 04, 2015 9:05 pm
My carbs were leaking a bit so I'm in the process of freshening up the gaskets. My current set up is dual holley 750's (#4779-9 --blower carbs?) on a 383 stroker with a 671 blower. Anyone know what the float levels should be for a holley 4779-9 carb? Closest I can find is for a 4779-2AAA--it's 13/16" for primary and 1/2" for secondary. But from what it looks like the previous setting was closer to 11/16" for the primary (haven't done the secondary yet). Would a custom tune have this much of a difference in levels? Thanks for any input!
