I have been building a twin engine go kart over the winter and it is nearing completition. It is powered by two Tecumseh HS50's. I built the hs50s with billet rods, new rings, seals, etc... I milled the head down a little to bump up the compression, fabricated a intake for the mikuni and opened the ports up. The carbs are 22mm mikuni taper bores. I plan on running high octane fuel. What should I put in it for jets? I am trying to get as much power with this combination as I can. Where can I buy jets for these carbs and does. anybody have a diagram of these? Here are some pictures of my build.
