Make sure fuel is getting to the engine. You can also check the fuel filter for blockages. In cold weather, it's not unusual for the fuel to gel, preventing the engine from starting. Add some fuel line antifreeze to the fuel tank and let the engine sit for a while. If the engine still refuses to start, other components might be the culprit. Consider a flooded engine; remove the spark plugs, crank the engine for a bit to clear out the excess fuel, then reinstall the plugs. There are many reasons why a snowmobile won't start, so try all of these steps.

Engine Performance Issues

Poor engine performance can ruin a day of riding. This can manifest as a loss of power, rough running, or stalling. Check the air filter for dirt and debris; a clogged air filter can restrict airflow and cause performance problems. Inspect the fuel injectors for clogs. A faulty fuel injector can cause the engine to run lean or rich, leading to poor performance. Examine the clutch. A worn or damaged clutch can cause a loss of power and poor acceleration. Look for wear and tear, and also check for any loose or broken parts. Check the compression. Low compression can cause the engine to lose power. Use a compression tester to check the compression in each cylinder. If you've been riding hard, and now your engine isn't performing well, it can be a frustrating situation to fix. So follow these easy steps to get you back on the snow.
