I even had this on a racing 4cyl with a light flywheel as well as nearly every Race engine we ran on track.Often a shift to the next gear stoped it.Ther was always a certain RPM that it occured usually when barely touching the pedal.Violent pulses,Im sure not the best at driveability,but it was never a problem when I didnt have a big stick in ther.So any ideas on the off idel lean spot?A different power valve maybe?
