go to home depot or lowes and get the same size tube that comes off of the carb and run it to the top of the snorkle. never heard about the airbox filling up with gas. if yo dont want the hassle of having to rejet twice then wait. there is a product called dial-a-jet. dont know if you have heard about it but you jet your four-wheeler and if you add something or go up or down in altitude, then it has a dial you turn to adjust, kinda like rejetting. i think thats how it works.
