Being involved with a international company producing industrial vehicles, I see a lot of this sort of thing. We source out thousands of parts from all over the world. Cost is a major consideration when awarding a bid from a suppler. quality is always a compromise. Most likely American Sportsworks found some company sitting on a bunch of carbs originally designed for some obscure small cc 4 stroke. They did a little R&D. The ports and the needle/seat were smaller but The carb fits fine and all they had to do was change the jetting some to put it in a marginally acceptable range. Did the carb produce optimum performance or ideal compatibility? No, but the cost per unit looked great on the bottom line! I'm thinking of a line from a movie, some astronauts siting in a rocket! " We're sitting on top of 10,000 gallons of rocket fuel in a machine with a million different parts supplied by the lowest bidder!"
