Hey y'all! My parents are letting me work on our year old to try to get it running again. It's a 2011 Gear Up Patrol, and this tube that's connecting the two carburetors has a sort of T- connector and it looks like one of the ends is open and pathetic used to have something connecting to it. I've tried Googling and youtubing it but I can't seem to find out what it's for or if it should be open or plugged? Any help would be greatly appreciated!
