352 carb trouble
Gentelmen,
I have a '66. Came with a 74 model 2100 2v carb with manual choke. It ran a bit rough so I bought a rebuilt kit and went for it. After installation, upon starting, the engine races all out and won't throttle down. The float setting is at 17/64 and is not flooding or leaking fuel. Any suggestions on what might be wrong? I am thinking maybe power valve gasket but was careful with intallation. What else could be allowing that much fuel into the venturies?
Thanks
JAKE

If the engines revving up out of control it's getting air from somewhere. Do a good visual on the butterfly's, gasket surfaces, any plugs that may be off.
A common problem on older carbs that doesn't get covered in a rebuild is a worn throttle shaft. Air can get in there and play hell with the idle circuits, but I never heard of one leaking enough to feed the motor.
