Thought you were summerizing them for next winter. You know get all the gas out you can, put in some stabil, run it till it runs out of fuel and store it.
you know, I never did that to my sleds. I would start them and warm them up about every 6-8 weeks, rotate the tracks, at times add fresh gas. They sat outside, undercovers, on a trailer. Starting them discouraged rodents and such from taking over.
