These precision carb re-calibration kits allow full range tuning without sacrificing reliability. The kit includes needles (early and late styles) with adjusting washers that help eliminate flat spots, main jets (150-190), main jet holder, slide spring and instructions.
Similar to the dyno jet kits but half the price. You're welcome folks.
