After the summer make sure you remove all the fuel in the tank. This will reduce buildup and any condensation from themp changes.
If you really a good mechanic at the end of the summer season pull the plug and clean it and squirt a little oil down into the plug hole before reinstalling the plug. This will help keep the rings lubricated on the top of the cylinder and less chance of seizing of the rings.
A few idea from me.
I have to respectfully disagree with you on several points "as a mechanic"
DO NOT run carb dry for winter storage .
DO NOT drain tank for winter storage .
Draining the items as you say introduce air and moisture to accumulate .
adding fuel stabilizer such as sea foam or stabil, I recommend sea foam and running unit till it mixes well and into carb .
then fill the tank completely full . then fogging the unit with the sea foam with a sprayer bottle .
I own 5 snowmobiles that I do this to every year. 4 carb. models and one fuel injected . The times anyone has ever had issues is when everything was drained dry .
You are asking for trouble when draining .
