Sta-Bil fuel additive should be all you need.
Add the Sta-Bil to a full tank of gasoline. Pull the spark plugs, spin the engine overview about 30 seconds. Put the clean plugs back in. Run water through the engine and fire it up, should be good go!

Change any fuel filters. Both external and internal.
