Our friends at Black Magic Racing reminded us to remind you to go out and start up your sled, like right now. Seriously. Where is your sled and how did you put it away at the end of the season? Did you take the gas out of the carbs? Did you fog it? Have you started it once a month like you should?
If not, it would be worth the effort to take 10 minutes and do this. We are not kidding. The gas that you left in it from your last ride is most likely shot. After as little as 2 weeks in the vented tank, the â€œlight endsâ€ of the fuel (the good stuff) floats away and the gas is losing its octane big time. The carb jets, especially the pilots, are turning green and slowly plugging up. The main jets are leaning themselves out and by fall, a 470 main jet could be reduced to something silly like a 270. You know what that means; lean seizure. If it starts at all, that is, as plugged pilot jets will pretty much keep the sled from idling.
Here at SnowTech weâ€™ve found dropping a Fitch Fuel Catalyst into the fuel and running this treated fuel into the carbs to be the most effective way to keep the fuel fresh and the carb jets from turning green. You can do this with a gas can, or use the sledâ€™s fuel tank itself, as these devices constantly â€œcrackâ€ the heavier fuel molecules into lighter ones, helping to maintain fuel volatility in storage environments.
Black Magic suggests adding a small amount of fresh fuel once a month and starting the engine to keep the seals lubricated and from drying out, as well as to keep fresh fuel in the float bowls. Bring it up to operating temperature to burn out all of the moisture, but donâ€™t run so long that you overheat it. You will be glad you did and sad if you didnâ€™t!
