It’s finally time to get those sleds prepped for the season! We know there are more than a few of you who cut down on the cursing, attend an extra church service and pray to God that your sled starts for one more season. We’ve been there!
There’s nothing more demoralizing than breaking out the sled in autumn only to find it’s not running correctly or maybe not even starting at all. Often the assumption is there’s something mechanically wrong. That’s entirely possible; however, if the engine was running well previously, it’s very difficult for a mechanical malfunction to occur while it’s not running for several months.
The more likely culprit is fuel degradation. That’s why many swear by the practice of draining fuel tanks before summer storage, but that’s a different debate. We’re just talking about what happens to the makeup of fuel over time and what can be done to prevent it. Consider this a chemistry lesson of sorts.
