Fuel pooling under secondary hanger - normal?

(1/2) > >>

Shark Racer:
I've never paid this much attention to a q-jet before. So when I was checking for nozzle drip (I have it, or something resembling it), I saw that the secondary rod area (where they pass through the gasket in the air horn) had a pool of fuel. Is this normal or no?

If not - where should I be checking?

Thanks much!

Zac Agee:
nozzle drip is on the primary ventura's inside the booster rings and on the brass, fuel gathers on them then drips off its very noticable you shouldnt be able to see any exessive wet/fuel driping from that area unless you have nozzle drip.

Shark Racer:
Thanks Zac - is the fuel around the airhorn gasket where the secondary rod passes through normal?

Zac Agee:
the holes in the air horn that the seconary rods go thrue lead directly into the main fuel chamber so fuel should only be as high as the float setting... fuel shouldnt be any closer then 1/4 of in inch to the bottom of the air horn, the gasket will be wet in there no matter what but fuel shouldnt be any closer then 1/4 of an inch under the gasket

Shark Racer:
This is a late model QJ on a 78 vette and the float setting is set at a 1/4". Just found an old post by Cliff that you should only run the high float setting with non-OEM parts as the OEM fuel pumps flow a lot more.

I guess I'll try lowering the float this weekend.
