Stabil doesn't always work. plus the gas continually evaporates all winter and left with junk come spring.

And another thing you want to be concerned with in cold weather is any remaining water in the cooling jackets. Freeze = cracked block or heads.

Another thing you can do is start the motor cold start first of the day out of water. Have intakes exposed and quickly spray a liberal amount of fogging oil into carbs, it will sputter and smoke like hell, it's supposed to but just keep RMP's up "slightly"

do it quickly in all carb intakes.

"disconnect gas line from tank"

motor runs till carbs are sucked dry. when they run dry the rpm's will pick up from leaning out and then the motor will sputter to a stall. you don't want to run them out of water for more than a minute or so first start of the day. The fogging oil keeps everything lubed well and protects it a bit while you do this.

Empty carbs are as good if not better than sabilized carbs. I do it with all my stuff for winter storage. Come spring, new gas, start it.

out of water also helps blow out any excess water in jackets.

if you can get to your water cooling system and poor or force marine grade anti freeze witha plastic 2 liter bottle made into a squeeze setup and force itin till it comes out the return never hurts either. Some motors have adapters to do this some don't.
