Throttle Lever
Squeeze the throttle lever toward the handlebar and then let it go. The lever should go right back to where it was before you squeezed it. If it goes back slowly or stays close to the handlebar, you have a sticky throttle. This means that something is wrong or broken.
WARNING
Don't start the snowmobile until an adult fixes
the sticky lever. You could get hurt if you ride with a sticky throttle.
