: Fellows,
: I was getting little brass shavings in my Zenith carb bowl.They'd work their way around in there until they would clog something and shut the car down.The shavings were coming from somewhere in the carburetor itself.As the GAV needle is the only significant moving part in the carb, I looked there.I found that the GAV housing was too tight where the needle protrudes form it.There was scoring on the needle in that area.This must have been the source of the shavings.
: The needle and housing were repro parts.The repro housings have a little steel ring around the base.Did the originals have this steel ring?I read that one should remove this ring when installing a new housing.I bought another new needle and housing, but this time I removed the ring.The valve works much easier now and I haven't had a shutdown yet.Could the solution be so simple?Has anyone out there had a similar experience?Any feedback is appreciated.

Brian,
I suspect that the troubled housing has a burr from when the slits were cut. I find many repo parts are sooo close but just miss the mark in small over looked details. More than likely the new one has a burr also, you should take it apart and check as with every part for your A, do not take them for granted. The steel ring is to give friction to the GAV to hold adustment while driving. Knew a fella that was tortured, his car would run OK for awhile thing go to pot, he tried new plugs, condenser, etc etc etc. It turned out to be the GAV, no ring. I guess it must have been too tight so who ever took off the ring but after awhile the housing relaxed and wouldn't hold adjustment.
