My friend has this old skidoo that didn't have a spark. I replaced his coil and wires so now there is a spark and it starts. It doesn't idle at all w/o the throttle applied and gas spits out of the carb. by the airbox. This sled has been sitting for about 4 or more years. Could it be that the gas is just REALLY bad i already know it is) but would it have that effect? If some1 could help me out that'd be great.
