1. The engine is not getting enough fuel. This could be due to a clogged fuel filter, a dirty carburetor, or a problem with the fuel pump. If the engine is not getting enough fuel, it will run lean and may stall or even overheat.
2. The engine is not getting enough air. This could be due to a clogged air filter, a dirty carburetor, or a problem with the intake system. If the engine is not getting enough air, it will run rich and may stall or even backfire.
3. The engine is not getting enough spark. This could be due to a bad spark plug, a bad ignition coil, or a problem with the wiring. If the engine is not getting enough spark, it will not fire and will not run.
4. The ATV is being operated in cold weather. When the temperature is cold, the engine may need to be run with the choke on to provide it with a richer fuel mixture. This helps the engine to start and run smoothly.
If your BearTracker 250 ATV is running with the choke on, it is important to diagnose and correct the underlying cause. Running the ATV with the choke on for an extended period of time can cause the engine to run rich and may damage the spark plug or other engine components.
