i bought a 86 yamaha inviter that was in storage for 5 years. when i took it home and cleaned it up and tryed to start it all it wants to do is spit and back fire. what could be stoping the sled from running.

Dirty pliot, main jets and small passage ways in your carb. Don't forget to change the fuel filter after cleaning the carb.

hows the spark nice and bright blue? sitting for that long maybe the mag or
stator is corroded??. coil,wire compression all check out?

Did you check the exhaust for obstructions?

Another thing to check is the throttle over ride system (TPS).
