I have a good friend is suspects a venturi effect possibly causing it. He is
well more versed in that type of application being an engineer, so I am
deferring to his knowledge base. I'll keep the list informed on this one.
But as a side note, the venturi effect made be exacerbated by the methanol
in the gas.
Not sure on the fuel mileage.......but my car never got great mileage
because of the richness of the carbs.
