Thanks Matt. We found thr vacuum modulator was bad, new one should be in today, that was the smoke. Found fluid running out of it as well. Hoping to see how it runs later today. I will read through the Carter stuff. I get confused with the metering rods, springs, etc. Right now the 850 Holley works better.
Metering rod and springs does the same thing as the Power Valve and the power valve restrictors. Rods down is highway driving. Rods up is enrichment for wide open throttle.
