Jim Hupy-- going back a few responses-- the spring on the secodary air valve trys to CLOSE it. The air flow on the wider side of the air valve wants to open it wide. The spring combined with the vacuum pot want to close it. The dropping vacuum is timed via an orifice in the vac pot to limit opening speed. Rod height (enrichment) is a function of mechanical cam action based on air valve degrees rotation. To adjust air valve there is a wind up spring and locking screw to adjust spring tension. A larger orifice hole will also speed opening. Faster is not better though.
