Thanks for all the replies...

Timing I adjust depending on the fuel... when running 100 octane I idle at 14* total 35* all in at 2500, this is for racing and I would probably turn up closer to 40* with 110 but I haven't run straight 110 yet. When running 91 octane, 11* initial 32* total. I added a timing controller (knob) to my MSD system so I can adjust the timing easily since I am running different fuels at different times, also I may reduce timing a few degrees at startup to turn over easier. I'm on the black bushing in the dist with one heavy and one light silver spring...

No vac advance (which I regret now because it would run cooler on the street and probably get better mileage)... As I told Erik before, I'm idling (very lumpy) at 800 but will try to turn it up to 1100 and see how the vac changes. I've also heard the suggestion to drill small holes in the butterflies so the idle circuit is working at higher revs, but I don't think this cam is so aggressive I need to go there yet.

Pat, I'm running the straight squirters #31 right now, are you suggesting I go to the kind with the tubes sticking out? Also I have the big annular straight boosters instead of the small downleg variety. I was thinking the tube nozzles might cause better vaporization of the fuel if it's shot into the boosters instead of down the hole like the other squirters(?)

Also, from the symptoms, do you think the pump cam needs to be sooner or bigger or both? I think I have the brown cam in the #1 position on the secondaries (but I'll have to double check that)...

I have the bushings and springs you mention for the ignition curve... that should give more advance +28* in just over 3000... I'm worried about how this will run on 91 octane because that would have to put my idle timing only at 4* to keep me safely out of detonation?

Thanks for all of the advice all of you... this board is great!
