Re: 750 cfm Holley Carb Throttle Sticking at Idle... Only when Running
Well, I tried a couple of things tonight. I did unhook the secondaries to see if that made a difference......it didn't. I also reoriented the throttle return spring so that it pulled opposite of the gas pedal linkage. Again, no change.
I removed the carb again to try to figure out what is going on. I did figure out that the secondaries were catching on the baseplate gasket a little. So, I replaced the thick insulating gasket with a regular one from Mr. Gasket. I tried pushing, pulling, twisting, and whatever else I could think of doing to the primary throttle shaft to get it to bind, and I just couldn't get it to, no matter what I did.
I also played with it some more while the engine was running. Its just weird....with the engine running, the throttle linkage is really rough feeling near the idle position, but then I shut the engine off and its as smooth as silk. I even called Holley and they were clueless. They couldn't even make any suggestions. I'm baffled.
