Here is what I consider the BIG problem. To make this carb identical to the other three, all three holes would need to be plugged and redrilled. The pics is not to exact scale, but the proportions are right. I am afraid of drilling the new holes so close to the old holes, filled or not. I know pierce does this, maybe to drill the 3rd extra hole that most need. But they may not want to get involved in this one
