I'm trying to find out how to get a basic tune of the mixture screws. I've seen two methods described. 1) adjust the mixture screws out to reach the highest manifold vacuum. 2) adjust the mixture screws in to reach the highest RPM. Which one is more accurate? and is there more to these procedures? Thanks all Robert __________________ Robert 1975 C10 - Huckleberry 2007 Jeep JK - John Wayne Jeep Smittybilt front/rear bumper, 10K winch Pacific Grove, CA
