I finally got my freshly rebuilt 350 installed and the cam broke in. Now that I am trying to fine tune it, I can't get it to idle at the right RPM. It idles way to fast. After it warms up, the idle does drop slightly, but not low enough. I have the screw in the carb adjusted for the lowest idle already. I tried spraying carb cleaner at the sealing surfaces with the engine running and had no change in engine speed. I was told I will have to pull the intake manifold off and use RTV on top of the gaskets. Before I do all that, I figured I would see what you guys say. BTW - It is a 76K5, rebuilt 350, used Holley aluminum intake manifold, new Truck Avenger carb, new Accel HEI distributor. Thanks for any help.
