Quadrajet - High Idle

<< < (3/3)

jmabrao:
My carb has front and rear vacuum breaks, the secondary damper is attached to the rear break. So I ordered a new front and rear vacuum break, should be here in a few weeks. I have noticed a bog if you stomp the throttle too quickly.

Cliff Ruggles:
I didn't see an order come in?

We modify the rear vacuum breaks as NOTHING currently being sold will allow the secondaries to open smoothly.  The ones currently being supplied so not have the correct restriction in them and will not prevent the secondaries from causing stumble/hesitation/bog when you go to full throttle.......FWIW....
