After drilling the various restrictions and tapping the idle tubes into place, we used several components of the rebuild kit to ensure reliable operation. This included a new needle valve and seat, foam float, accelerator pump, and fuel filter. We richened the power portion of the primary circuit by replacing original jets with a pair of 0.073-inch units from the kit.
