Holley Carb Help

[Lumpy]

Hello,
Is there a way to adjust the vaccuum secondaries on a holley 750? Thanks.....Lumpy

Yes there sure is, go to your local speed shop and buy a vacuum secondary spring kit and change springs until you get rid of your problem.

Thanks Sgdiv,
One more question. Why the heck would someone put a vacuum secondary carb on a boat in the first place? Thanks

Probably what that someone had lying around. They work good when you get them dialed in. Usually have to put a very soft spring in.

Your right Lumpy most boats have progressive secondarys. If you have a bad one take them off and put on progressive Originally posted by Lumpy:
