Avs 4425s vs 4615sa

when that carb came out the chrysler factory racers found out that the air valve above the secondarys was set to loose. they set the spring tighter fixed the trouble. the resetting is a little tricky. the factory has a spacial tool but it can be done by hand with some care. and i have found that AFBs and AVSs like the float setting of 5/16 works good.
