[QUOTE=Cliff R;6521709]Do NOT disconnect the link from the pull-off up to the secondaries. I see folks recommending this all the time and it will not work. The pull-off is there to provide smooth transition and it must be timed correctly for this to happen. Problem is that dating back at least 20 years now the pull-offs being supplies do not have the correct springs in them nor the correct restriction in the orifice so they work correctly. Take the white plastic pull-offs currently being supplied for the early 67-70 Q-jets. The spring in them requres 14" vacuum to apply the pull-off, factory spec is 5"-6".
I've tried to get the manufacturer's to correct this issue but it goes on deaf ears. I used to modify them in house but currently sending them out to be "rebuilt" with the correct spring and orifice in them.
All the pull-offs I sell are modified to work correctly, next to nothing coming from the manufacturers is worth two squirts of duck poop right out of the box......
Back in 70's, we use to disconnect the pull offs so we could get immediate secondary openings. I was told to do this by a co-worker who had a 69 RAIII GTO then. Sounded good at the time but it was bog city when stomping the gas during street races. We didn't know any better back then. Today, my Qjet was set up by you and operates as it should with no noticeable bog. The things you learn over the years can be rewarding if you pay attention!!
