I had 2 of the 4 float bowl screws turning free and not tightening. Replaced all 4 with M5x20 stainless metric allen screws. Thread count is the same, but the metric is slightly larger diameter. Ran them in and let them self-tap. Had to drill the holes in the bowls ever so slightly larger so they would spin free. I used slightly longer-than-stock screws so they would go all the way through the newly tapped holes in the carb bodies. Worked like a charm and didn't even have to buy a tap.
