There is no exact setting for the butterflies and barrel valve, it varies with each combination. It's a little back and forth game, find the butterfly opening that gives the correct idle speed, then find the correct barrel valve setting that gives the proper amount of fuel at idle so it goes up on the converter clean. I set up at 2 flats rich from a clean hit on the transbrake, which happens to be 22%. .002 on the butterflies, idle out of gear at 1150, 1000 in gear.
The drop in vacuum could easily be caused by the oil being stripped from the vanes in the pump. I have found it best to drop a couple of ounces of oil in the pump before I fire the car for the first time that day.
Try not pulling the handle out so much.
Thanks ccperf.
I will double and triple check everything you mentioned.
I'll check the idle and the barrel valve leakdown and flush and lubricate the vacuum pump. Although the pump was working, because it was forcing steam out of the breather vent...like a steam engine.
I would think at 60 psi idling fuel pressure, all nozzles would be getting fuel.
I'm running an Edelbrock Sr intake.
And i will not lean it as much as I did. I'm sure I over did it. Hence the header discoloration.
