Yeah. If it's a new engine, go ahead and run it through two or three tanks of fuel. Won't hurt anything, but will help because you won't have to do it when it warms up and you are ready to fly the thing. Don't forget to follow the engine manufacturere's guidelines for break in... break it in rich!! Enjoy your time with the engine. It will give you more incentive to get out and fly it when the weather does improve.
