Carburetor Question

I currently have a Holley 4BBl carb that keeps getting the timing out of whack. I have had it with this carb and I am looking for a new carb. How much power will I lose if I go to a 4BBL carb? The Jeep has an Offenhauser dual port header. If I go to a 2BBL carb, do I have to change this as well? Many thanks!

A carb will not effect your static timing. While you didn't tell us what engine,carb,or dist your running, the only thing the "carb" can effect is the vacuum advance. If your having timing issues, I'd look at the dist or timing chain, or a possable computer problem, if it is still equiped with one.

X2 Carb mixes fuel and air and delivers the mixture through the intake manifold. Possible vacuum leak somewhere. What kind of distributor are you running? A little more information please. Thanks Scot

Some Holleys have a spark vacuum port that is supposed to supply vacuum at higher than idle speeds. As hard as it is to get the mixture properly set on some Holley carbs I wouldn't be surprised if the spark vacuum port (if it has one) isn't working properly.

The old Offy dual port manifolds work best with a 4bbl carb. A 2bbl carb will still work, but a good 2bbl carb doesn't really cost more or less than a good 4bbl carb, so if you want to use the Offy, find another 4bbl.
