Clois,

Did you fix your problem? I think that I am having the same problem, which was diagnosed as a lean condition at full throttle caused bu no fuel from the secondaries. The primaries work great, but when the secondaries open at 3500 - 4000 RPM they do not add any fuel. After 4000 RPM the fuel starts to come in, but still not enough to make the mixture right.
I am going to try a stiffer step up spring, and bigger secondary jet.

Mr. Fixit,

You mentioned the secondaries opening too soon, is there a way to ajust that on the Edelbrock Performer carb?
