ugh replaced the float needle and seat with the correct one now i cant get it adjusted. either wont seat and leaks fuel from the overflow and jet on the side. or it starves for fuel. top carb markings are 631061 WE9-1 11/86 middle carb 632061-1 WE18-2 12/86 bottom carb 632061-1 WE18-2 1/87. I am assuming the PO swaped the top carb I would like to find a set with the better float needle and seat, because the rubber seat with the retainer clip sucks. Any explanation of the part #"s would be helpfull in my srarch for a carb set
