GTO Geoff, I have tried reducing the idle jets in the past without any positive results, but that was with the faster timing ramp so it's now on the list of things to experiment with.
rgalajda, I did try the 70 IAB's and I did readjust the idle mixture without any noticeable difference. I obviously wasn't thinking clearly on that. I went back to the 72's when i slowed the timing ramp thinking i'd be testing the original tune on the carbs with the timing change.
We're supposed to have some better (cooler) weather this weekend so i should get get some quality time to play with it.
Thinking my 2 options on my plan of attack:
(A) Adjust idle mixture, and test again. Curious, how do you folks approach it? I have adjusted for highest smoothest vacuum, the mixture screws are very sensitive when there are 8 of them lol
If there is a noticeable and improvement i may leave it alone, if its better but not quite there maybe increase the IAB and retest (without readjusting mixture)!
If there is no improvement then i'll reduce the IFR's, readjust and test again.
or
(B) Just say screw it and go for the IFR change first and go from there.
If/when I try smaller IFR's would going from .031 to .028 be too much? Would it make any sense just to change the primary side?
