Nice work, TL! That's a good fix. I did it to a "full resto" of an early K1 the owner wanted to keep all-original as possible (he was one of those vintage car collector guys), and one of the carbs' tangs had been corroded away from water sitting in the carb bowl a long time. I managed to get the brass floats' holes all plugged, and made a new tang altogether, soldering it to the round tube the pin fits in. It has held up fine for years, so I know your fix will, too!
