HALP Quadrajet dribbling

[Sandy]

The beloved QJet, my favorite carb!, A couple of things can cause the
dribble. Some QJets have bad seals under the wells for the pri jets, Check
under the main bowl for fuel leaks. Most QJet books show some repair for
this, the second thing is to check the accelerator pump as it may be
missing the ball bearing that stops fuel from getting sucked into the
engine (I think this is true, been a long time), Check for vacuum leaks
and general top gasket leaks, and use a vacuum gauge to see if it is
steady, if not, your enrichment circuits (the piston with the needles
attached) will pop up and will cause fuel to pour in. If this is the case
you will need to bump the idle a bit or find the leak, maybe bad pvc or
hose. Also sometimes you can cheat by bumping the timming to get some more
rpm at idle.
