Hello, its starting to get cold here in michigan. at some point it will be time to put the bird away for the winter. What do you recommend i do to the engine ? should i start it periodically throughout the winter to get fresher fuel flowing through the carb and oil throughout the engine (put stabil in it?) ? or is it better to just let it sit for 3 months without starting it ? i'm concerned about the gas going sour and gumming up the carb. what do you all do ? thanks
