That's totally incorrect. Tha AVS carburetors are MECHANICAL SECONDARIES that are controlled by an air door. The "how much" and "how hard" the air door is to open controls air flow, but the base plate opens the secondaries mechanically. Your guy is dead wrong. I and several others have told you multiple times now how to adjust your throttle cable, that it is not adjusted correctly. We're not saying all that just to be wasting our breath. You obviously have someone who doesn't know what he's doing working with you. I suggest you find someone that does. Steve, maybe there's a willing member in your area who would come take a look at it? Maybe buy the beer and hamburgers.
