Chassis Dyno Questions

Thanks Moper. Do you know of any product available to fine tune carb/engine at home? I have no problem welding a couple bungs to the collectors. I've rebuilt several engines and have been playing with cars and motors for about 15 years now, but I never feel like they're tuned right. I also see other cars at shows that idle nice, startup real nice, and don;t smell rich and make your eyes burn:-D

I'd love to be able to drive my car to work on occasion and not smell like exhuast for the rest of the day.
