vacuum break control

<< < (2/2)

Vics63:
A couple of pictures of the 2 different carburetors showing where the vacuum line to the pull off is connected. Am I correct in calling this ported vacuum?

Kenth:
No, both your pull-offs are connected to constant manifold vacuum as they should.

Vics63:
Thank you for the replies. I've learned something new today. I've spent all morning reading up on this and it sounds like the only ported vacuum is on the front drivers side of the carburetor? That is where the vacuum advance is connected on both of them. So the pull off releases when manifold vacuum is lost but it seems very slow when I disconnect the vacuum to watch it. I would love to see it in action but I don't know how I would accomplish that.

Cliff Ruggles:
Get rid of the rubber hose on the pressure side of the fuel pump, very dangerous especially how fuel tends to "eat" rubber these days.

I also see general use of Teflon tape.  ALL of the connections used on the Quadrajet either have gaskets (fuel inlet housing) or inverted flare (fuel lines).  They do NOT need any additional sealant and Teflon tape can and will find it's way into the carb and cause issues........Cliff
