Dirk,

I think that you are referring to the plastic float shown off to the side 
and not the metal one nearest the carb. I talked to my second expert today 
about that plus a very well qualified parts guy. they concur with Eric's 
photo. I don't know why he had the normal HS plastic float off to the side.
