hey guys I just bought a 04 rhino from my b-inlaw.440 miles.he just putted around with it.one time he had a problem with fuel on a hot day.mem.day 90degrees.I could not keep it running. quit 3or4 times.had to wait it out. when I got it I changed all fluids,plug cleaned an oiled air filter,added msd charge new fuel filter.today I put on some clear tubing to watch it.lots of bubbles Ialso added a marine primer bulb to help on starts after it sits for a while.at a little higher idle it spits back through carb and dies.seems more fuel goes thru return line than carb so pump is working ok i guess.I would like to see pic.of y fitting placement.mine is same as factory diagram.Don,t mind throwing money at it but if I cant get this worked out I,ll sell it on a cool day and go back to my trv artic cat !!!sorry for long post but I needed to vent also.thanks.
