Well, looks like the carb on my old Sears puddle jumper is finally plain worn out. I've had pretty good luck with aftermarket carburetors, but I'm not finding any replacement #s for mine. The engine is an HS40 55515G, carb part # is 631667. I've got plenty of mower/snowblower carbs laying around, but obviously I need one set up for a minibike, right? Throttle response? Jetting? I'm assuming that's why I can't use one of those. Anyways, can anyone recommend a good aftermarket carb # for me? Thanks in advance!
