Got my fuel line hooked up today after my carb/intake/spacer install, and the carb is idling insanely fast, i have no tach so i cannot tell exactly but i would guess around 2000, so i shut it down fairly quick. Is this the fast idle of the carb or something i may have done wrong with leaky vaccum or what?The intake is a rpm air gap and the carb is a 670cfm holley, with a 1" 4 hole spacer, on top of an otherwise stock 351W

What kind of throttle linkage do you have.My 65 when I put a spacer on it moved the rod just enough to push idle up.Adjusted rod to not pull on carb. linkage at idle.You should have a tach and I hope your running temp. and pressure gauges as they relay vital info from your engine.

Dumb question but, do you have the return spring hooked up?------------------

Are you sure the carb was closing all the way,or maybe the choke or fast idle was stuck on------------------

Is your carb sealed around the base. I put a new carb on once and the gasket was crap. Didn't seal around the base and it idled to the moon.

it's a new intake and a new spacer, and all new gaskets, so i would think it should be sealed.Where can i get a throttle ball deal to connect the throttle cable to? I cannot get the one out/off my old carb

I also had this problem and it turned out to be the carburetor gasket. Ended up going through 3 of them before I just bought gasket material and made my own. Might be worth another look at yours.

You can get the carb balls at any big speed shop near you. ------------------
