    The SPRING-00002-L/R-1 can cause wear to the throttle shaft and introduce additional friction that prevents the ability of the spring to pull the throttle to full open. To prevent wear and improve this operation, a retaining plate was designed for the spring to be captured in and serve as a bearing surface for the inboard leg.
