    89 yamaha exciter 570 carb issues

    I just bought a 89 exciter and I can't figure out where a couple hoses go from the carb, it runs great but there is gas leaking from the carb on passenger side from two fuel lines that where just sitting there pointed down. Not sure if that is normal, I'm pretty new to snowmobiles, I can rebuild small engines and V8s all day long but this is new for me lol

    Those are the vent lines to equalize the pressure in the float bowl. Sound like you have a stuck float or a bad needle valve. The bowl is overfilling with fuel.
