Thread: More Edelbrock Hot Hard Starting Problems

Tweet

I changed the float level from 7/16" to 1/2" but now it doesn't want to idle at all or run very good. Did I go too much or the wrong way?

You went the right way, increasing the delta which drops the level. However, the float level is what establishes the static head on the jets, and it sounds like your engine is very sensitive to that static head. You might be able to rejet the mains and adjust your idle mixture to account for the lower level, but it's going to be some hassles. If it were mine I would put it back at 7/16" and chase the heat problem. Do you have room to put on a metal heat shield beneath the carb that extends out and up from the manifold to reflect the heat away from the carb body?

Well I'm ready to chunk the Edelbrock. I just don't know whether to have my Quadrajet rebuilt and tuned or buy a Street Avenger. Any thoughts?

Buy the Holley. Had the same problems. To much heat under the hood. Motor to hot. The Holley works fine. Gave the edelbrock to a guy with a 289 in a T-Bucket and it works fine.
