Hi everyone, new to the site, looks awesome. I just sold my SXI and have to get my old 300 going properly to sell it. Going to buy a new Superjet or SXR depending on how the test rides go. Does anyone remember if the JS300 with the round Mikuni carb has a restricter in the fuel return line to the tank. Mine is pumping all the fuel back to the tank and it only runs at WOT if I block off the return line, otherwise it will only rev to about a third throttle. Thanks guys
