Well that's better info on your bing, did you try polishing the seat in the carb body with a pencil eraser?
That will fix most leaks.
To set the float i hould the carb upside down.
And set it so a dime will just clear it on the far side.
And the tang/wings at the bottom of the bowl can snag the float if the B on the bottom side of the bowl is not lined up with air filter or the intake side of the carb housing.
