I'm no expert, but I'd have to think your drive belt is to tight. Get the number off your drive belt, maybe a picture or video of your set up and post it. A call to Tom at CPP (site sponsor) would help also. He is the "BigBlock Guru":thumbup:

Motor should idle below 1500 all day long. I once forgot and left my wifes big block idle for 3 hours, never missed a beat. I usually set at 1000-1100 rpm either the mixture screw needs tweaked or idle passage is still blocked. When setting idle make sure you set it with the idle speed screw and leave a little slack in the cable.
