one word of caution using that, CAREFULLY; be sure to take like a pair of vise grips and open up the jaws so the float pin will fit in the opening, place the vise grips on the opposite side from where your using the auto punch, push on the vise grips towards the auto punch while using it, this will keep from breaking off the float tangs off the carb rack, seen that happen more then once before, then you have a junk carb rack.
