fuel in vacuum advance canister

Well Ive figured it out! Mderoy340 I think nailed it. The manifold vacuum sorce is basically below the transition slot on the mighty demon carbs! Took the ol girl out for a drive. Run loke a scalded cat. Came home pulled vacuum line off distributor & dry. Then pulled vacuum cap off carburetor where I was using for manifold sorce and sure enough fuel in my vac cap! It has started to soften the rubber vacuum cap! SO there is somthing goofy with the manifold vac sorce plumbing/design on the demon/barry grant carburetor base plate I see. Just an fyi to all those who have one. There AWESOME carbs but go the the intake manifold itself for a manifold sorce!
