Flyflinger, sorry to hear about your mother-in-law. My thouhgts and prayers will be with you all. As far as your motor goes, I'am no expert but I would think if your not going to be using it for along while you could just fog it like some people do in the winter time. I would for sure put some kind of stablilizer in your gas if you have much left. Not much help but its all I really know. Take care buddy.
