I have a holley 4160 650 double pumper on top of a 318 with a racing cam and some head work probably with a compression ratio close to 10:1. The idle timing is set at about 12 degrees. Right now I'm having troubles getting the car to idle below 1500 rpms. Also while the engine is running there is gas dripping out of the booster venturis. is his suppose to be happening? and if it's not what needs to be done to fix it. ive checked the float levels and just took the primary and secondary fuel bowls apart and cleaned the metering blocks and replaced fuel valves.
