Just to look at it,It looks like all the correct parts for a Yamaha C85 Carb. The First thing was the float height was a little low in the closed position and did not drop low enough in the open position. Tried using the old float and it was now worse.(That should have a red flag) I modified (sanded)the stops on the back of the new float so it would open properly and ignored the slight difference in the closed height. Assembled and All the carbs flooded! I couldn't believe the slight difference in the float height(1/64in) allowed this to happen. Took it back apart and looked real close to find the needle valve keeper/spring was touching the needle valve seat preventing from closing all the way. So I say this would not work on any carb. It appears the hole in the valve seat is too low or drilled out too far or the wrong one all together.
