Carb Choke Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

kens65fb · 11-04-2022, 05:38 PM

We just installed an Eddelbrock 650 CFM on my buddies truck.

When it starts in the morning the choke seems to work, but the idle is way to slow ( 600RPM) I've read that the high speed idle when the choke first comes on should be about 1200 rpm or so.

I know that the fast idle screw is located beneath the regular idle screw, that is where you can increase the cold idle.

What direction do you rotate the screw to INCREASE idle speed, clockwise or counterclockwise ??
