Did you put any kind of fuel stabilizer in when you winterized?
I have heard mixed reviews on the additives but most are in the snake oil camp. What about Marvel Mystery Oil? I know nothing about it's composition but could that help or hurt?
I do use Stabil on a regular basis both during the season and the appropriate amount for winterization.
