I currently have a 300 fourtrax that is snorkeled . It is all ran properly with new hose and tubing but my carb is still getting water in it somewhere when it get around the bottom of the seat or so . Got a vent line running out the side of the carb for it to breath and then drain tube is plugged up but it still dies underwater . But I can pull it out of the water and start it right back up without draining the carb or aorbow or anything . Please help I don't know what else to do with it .
