my holley 600 series (4150) secondarys are constantly dripping. i rebuilt the carb because they were doing this. obviously it didnt fix the problem. primarys are fine, as far as i know. car starts and runs. but obviously not that good cause the sec. are just constantly leaking.



it use to be vacuum secondary i think. everything on that side has been removed. there is a screw on the throttle linkage that that opens the secondarys the same time the primarys open. its called bridging the carb from what im told....



what could be the problem???

Check your float level, check engine vacuum(good and steady), and check the power valve and its gasket on that side.

has to be the floats

There is a place that I get my Holleys from that I can garauntee you will out perform any other Holley 600 you ever used. PM me if interested. Not RB.

lowering the float level fixed it. i just dont know how much i lowered it now. theres just a screw instead of sight bowls on my fuel bowl :(

Adjust on a level surface, bring the fuel up til its just cresting into the sight hole about to flow out.



Do this while the engines running of course.

cool, thanks...
