yes, just probably a simple mod at the factory could cure it. The AVS II's used to be offered by summit as "remans" as so many were returned. I think the idea is a great street carb. I think it just needs to be re-defined. I like the AVS/AFB style carbs, ran a lot of them with great success. Again, they perform great once going, and perform great just cruising, but they hate a dead idle smash of the gas.
