I had an opportunity to install an aftermarket distributor, and I did. Pulled the old one out and dropped the new one in. I did all the correct things to insure that the new one dropped in just the way the old one came out. My question is, how do I time the car? Is it according to the factory specs or is there another formula out there. Car starts fine, has a small flat spot when I goose the throttle when cold. Also, there is a noticable flat spot when I jump on it in 3 or 4 gear. I realize this all may be due to incorrect timing and carb misadjustment since the new distributor went in. Any suggestions or advice appreciated.
