I've got everything back to original with the timing of low speed to 2 degrees and max advance 24' degrees. What is the best way to adjust one carburator at a time. I have closed all 3 screws to seat...then back out 1-1/4 turns. At that setting it is about 3 seconds before start up. I back them out about another 1/2 turn and it starts immediately. It idles great...but it sounds like a muscle car getting ready at the light so to speak. Please keep in mind I am a fuel-injected mechanic...I have NEVER dealt with carburators at all. I have the manual but i would like some of your guys' info.
