The reason to fill the tank is that there is less/no room for it to evaporate.
It's the old gas that makes SO many sleds run like crap.
Once any of the fuel system varnishes up, it's not good.
Carbs at least you can clean easier. FI cleaner kinda works. But by that time its a lil late.
Also the reason for premium, octane loss due to the voc's that do evaporate.
The reason to change the pto oil is that you don't want the old oil sittin as it might have some h2o in it.
If not stored indoors, a cover for the sled is a good idea, Uv and weather protection.
Fogging the cylinders? If it's super humid where you live, maybe. But starting it would be better.
You could squirt a lil marvel mystery oil in to protect rings.
