CHECK THIS OUT CRUISE: (main jet a tad rich?) 3000rpms in 2nd gear= 14.8-15.0 60mph= 3100rpms 13.6-13.8 (added) 3500rpms in 2nd gear= 13.6-13.8 (same as 60mph)
It appears that the mains are starting in between 2700rpms and 3000rpms. My main jets (66's) might be a tad rich. I swapped out my .071 IABS to the current .075's after the first startup with the O2 kit. Should I go back to the 071's to bring the mains in quicker and to richen the transition?
TRANSITION: 30mph= 1700rpms 17.0 Off idle with a red pump cam and a 037 squirter, I am still getting a lean spike of 16 on the guage from a stop to light throttle. I believe that the 071 IAB's will help this too but I am not sure if my .028 IFR's are too lean too looking at the 30mph thru 55mph readings.
Thank you very much.
