Holley Idle Screws Not Responsive
Thank you very much good FABO guys for all of your suggestions. I was able to fix the problem by opening the secondary "a crack" with the set screws. I'm not sure of how but, I must have got that unit of measurement on the first try. I think "a crack" is more than "a smidgen" and less than "a bit". (thanks ramcharger for the instructions).
Along the way I did come to find that my Mopar electronic distributor had seen better days. I couldn't get the car properly timed because the timing was moving all over the place at rpm. I could not advance it past 28* total without it shaking all over. Maybe it was fixable but I splurged for an MSD Probillet dist, 6al Box, wire set and I already had a Blaster 2 coil. I put the box under the battery tray. I'm using the black bushing that allows for 18* of advance and now have the initial timing at 18* with 36* at full advance and I may be able to bump that up a degree or two. Considering the cam, 4 speed with a 3.91 gear, I set the rate of advance to the second from fastest. It seems to be a good starting point and I can fine tune it from here.
I'm very interested to see if there will be much improvement in performance because I went to test and tune last weekend (with the messed up distributor and untuned carb) and the car went a surprisingly fast 12.3 at 112. We will see. Thanks again for the help.
