I finally got the 70 running however she will not idle at alll. I have to keep reving to keep the car going otherwise it sputters and dies. The carb is a Holley 4160 DP, 800 cfm. I picked up a Holley tuning book from Haynes at the auto parts store and I look at some of the solutions to what my problem is and most of them have already been done (two holes drilled in the back two barrels, butterflly taken off, etc). The two screws on either side near the front two barrels which are supposed to let you adjust the flow dont work and I think thats because the car has to idle at above 1000rpm to stay running, thusly bypassing the idle circuit. Is it something with my floats or something else internally? The guy I purchased the car from said he had purchased a rebuild kit and had his father rebuild it for him however I have read that you should not use the generic over the counter rebuild kits for Holley carbs, and to get a direct one that Holley makes. Could this "rebuild" be whats causing my problem? Any help is appreciated!
