I disagree---the main jets are Carb 101, the rest is the advanced studies

Jerry,

All that stuff can be done with the car sitting parked in the garage with absolutely no tools or analysis. Selecting the right main jets requires the car to be at idle, . . . and under full load, . . . .and everything in between while being monitered with an oxygen sensor to measure fuel/air ratio, all while under load on a dyno. Also plugs must be analyzed. This is the essence of carb tuning for performance. What you stated is for grandpa to ensure that the care drives "nice" and will idle. It has nothing to do with maximizing performance.

Ed
