As the engine heats up, the symptoms usually intensify. When a stator fails, it produces a weak spark, which causes the engine to miss or perform badly. There would be no spark without a stator, and the engine would not function. On small engines, the stator coil produces the power for the spark plug and other accessories. Throughout the day, the sled gradually loses power. Runs poorly at low rpms yet well at higher rpms (Low speed coil going bad) At lower rpms, it’s OK, but at higher rpms, it’s a disaster (High speed coil is going bad) It’s backfiring and won’t run properly. If you have a battery that is too weak to power the machine, then there may be an issue with the stator. If your snowmobile stator is bad, you will see symptoms such as the engine will not start, or it will be hard to start.

If you notice it making grinding noises or if its getting louder than usual, then replacing your snowmobile stator might be necessary. The stator is the fan-like part that creates energy from an electric current and cools down the output so it can be used efficiently by your snowmobile engine. Snowmobiles have been a favorite mode of transportation for many Canadians, but they are also known to produce a lot of noise when in use.
