Once the snowmobile season has ended, it is time to prepare your machine for spring storage. A certified mechanic should repair any items you find that might need repair.
These are some recommendations for spring storage:
Lift the track and keep it elevated by supporting it with a board or a block so it stays off the ground
Place a wooden board under each ski to keep the skags and skis up away from moisture to help minimize rusting
Put the recommended amount of gasoline stabilizer in the gas tank so the gas does not become stale
Turn off the gas with the inline gas valve
Start the snowmobile and run the carburetors dry by allowing the machine to run until it quits
Other things you should check:

Bogie Wheels
Slide/High-Fax
Wear Bars on Skis
