Default Re: GAV Adjustment While Driving?

The setting of the GAV will be different for each car. The setting depends on the sizing of the comp jet and the cap jet. They are in the circuit with the GAV valve. On my Victoria I have it open about three quarters on a turn, and leave it there for normal driving around town. Out on the road when I encounter a long steep grade I open the GAV more and back off on the spark advance a little.

If the comp jet has been drilled out larger than the cap jet, the GAV will then have no function.
