Glad you got the leak stopped. Now is the time to set the float drop.
Understanding why an adjustment is made makes doing the adjustment easier.
The float drop adjustment is too prevent the float from hitting the bottom of the bowl (center section) if all of the fuel evaporates from the bowl.
So, measure the distance from the top of the bowl to the bottom of the bowl at the point where the lower part of the float would hit if allowed to do so. Subtract 1/16 of an inch. Turn the airhorn (top section) such that it is in its normal upright position with the floats hanging down. Bend the float arm tang such that when down the lowest point of the float is at your adjusted measurement. Now recheck the float level adjustment; easy to get the float level out of adjustment when making the drop adjustment.
Jon.
