Re: Vacuum leak?

I'm not familiar with a Quick Fuel carb but on Q-jets sometimes the secondary throttles don't shut tight. Like the guys said, spray some carb cleaner down the throats. I don't think it sounds like an intake manifold leak. Remove the PCV from the valve cover & see if you can feel a vacuum at the valve cover. That would indicate a leak in the intake gasket.
