A question for Mark Whitener or any other carb guys. Do you do anything different if you know that there will be another set of butterflies under it? I am asking because a neighbor is having consistency issues. In fact it often runs faster when the air is worse. It is a pro form 850 on a 496 with an Et genie underneath. Is it possible that the calibration of the carb is causing this? I feel he would gladly spend some money on it, but I will not recommend it if I am not fairly sure that it will help. He is going to run my off the shelf Holley next weekend and see if there’s any difference.
