Re: Zenith - 1 Carburetor
What is the GAV and where is it located? Thank you. David… by reading the posts I am thinking it’s the fuel adjusting needle in the choke driver as in the manual. If I’m wrong someone please let me know.

Re: Zenith - 1 Carburetor
Honness, You are correct. GAV stands for Gas Adjustment Valve.

I'm not sure what carburetor the instructions are for in post #1. As far as I know there is no "packing nut" on the GAV

Re: Zenith - 1 Carburetor
[QUOTE=Ruth;2039547]To add to your list, Throttle shaft/carb body worn and sucking air in. I find this most common on old carburetors. Oversize shafts and bushings are available.
I believe I might have updated this thread awhile back, but sorry if I did not. I found that the main jet was undersized, and opened it up with a #63 jet drill bit. It now works and runs perfectly @ 1/8 turn open of the GAV. Thanks for all the help.
