What To Do When Your Snowmobile Doesn’t Start?

Once in a while, a snowmobile may fail to start because of technical issues. However, you should not panic since there are troubleshooting methods that you can follow for a solution, from essential maintenance to diagnosis of faulty parts that may need quality spare parts from the Straightline Performance store. When your snowmobile fails to start, you should begin by checking the fuel, compression, and spark plugs. The difficulties that can make a snowmobile fail to operate are associated with these areas. Follow these instructions to troubleshoot your machine;

Assessing A Snowmobile That Won’t Start

When your snowmobile fails to start, consider checking the items below. Remember that it’s in your best interest to align with the instructions below so you can solve these common problems. Look into the following;

  • Address Any Fuel Issues

When a snowmobile has no fuel, it can fail to start. Begin by checking to see if there’s adequate fuel in your tank. It’s also worth checking to verify that you didn’t accidentally press the off button. Note that snowmobiles have gasoline shut-off levers to prevent your sled from launching when off. You should be keen on these typical features; people tend to neglect or overlook these switches. However, if your snowmobile has adequate gasoline but still doesn’t start, consider trying the following step:

  • Clear Fuel Piping

Obstructions in fuel lines block fuel from getting into your engine, and it cannot start without power. The solution is to detach the bonnet covering the engine area and closely inspect your snowmobile’s fuel system. If you notice coagulations along the gasoline line, physically clean it up for fuel to flow freely.

Turn off the engine and unscrew its spark plug when manually cleaning the gasoline lines. With the throttle wide, pull your starting cord multiple times. While at it, assess whether petrol is coming from the fuel system or not. If gasoline flows through the pipes, they have no clogging. Put back your spark plug and restart the engine. If it fails to start, proceed to the next step.

  • Replace Your Oil Or Fuel

Fuel and oil go bad when stored in tanks for extended durations. Assuming that’s the issue, the cure is straightforward.

Drain the oil and fuel and replace them with new supplies. Should the problem persist, move on to the next step.

  • Remove Fuel From Your Snowmobile’s Engine

Please remember that this procedure involves removing fuel from your snowmobile’s engine, not its fuel tank. When there’s a lot of fuel in the engine, the machine can get flooded(over-choked) and fail to start. Excessive gasoline can enter your engine as a result of various reasons. Follow these steps when removing fuel from your machine;

  • Switch off your choke and unscrew the spark plug.
  • Switch your fuel shut-off lever down.
  • Severally turn the power on and off to remove extra fuel from the engine
  • Clean Your Carburetor With Starting Fluid

The carburetors may dry up and accumulate dust when you leave snowmobiles unattended for extended durations. A clogged or dirty carburetor can stop your engine from running. Therefore you should consider cleaning it by following these steps;

  • For a few seconds, spritz starting fluid into the carburetor’s intake.
  • Note that excessive use of starting fluid can potentially harm your engine, so use it sparingly. Spray for about three seconds; it should sufficiently lubricate or clean the carburetor. 
  • After that, start your snowmobile to test whether it is operating.
  • Examine Your Snowmobile For Spark Plug Problems

A snowmobile will not start if it has a broken spark plug. Ensure that your snowmobile’s spark plug is in excellent working order. Follow this procedure when inspecting your spark plug’s health.

Open the hood covering your spark plug and assess its physical health for rust, cuts, or discolorations. These can indicate damages to the plug. Stress from heat and engine vibration usually results in these damages. Assuming you don’t see any deterioration, pay attention to the plug’s spark.

Follow these directions to make your plug produce sparks, then evaluate the results;

  • Remove spark plugs from the snowmobile’s engine, then connect them to your snowmobile’s frame.
  • Ensure and confirm that your spark plug’s wire remains connected to your plug even when out of your engine.
  • Next, try starting your snowmobile to see whether its spark plug creates sparks.

It would be helpful to know that if it fails to spark or generates yellow sparks, then your plug is faulty. On the other hand, blue sparks signify that your plug is perfect.

Remember that plugs work more effectively outside combustion chambers than within them; therefore, blue sparks don’t necessarily signify an excellent plug. Upon performing the checks mentioned above, consider replacing the plugs if they are damaged. At the same time, inspect your spark plug wires and ensure they’re in excellent shape. Vibrations can make the spark plug wiring brush on sharp corners, causing it to break. Replace the spark plug wiring if you notice that it has any cuts.

  • Examine Snowmobile For Electrical Problems

A snowmobile won’t start if its electrical system isn’t functional. Often, snowmobiles are on snow and can collect some particles. These snow particles can melt on the hot engines and leak into the machine’s electrical system as a liquid. Consequently, the liquid corrodes metal terminals over time, causing damage and other issues. Check the wiring system compartment to assess your snowmobile for these problems. Examine all of the cables and terminals thoroughly and keep an eye out for rust, corrosion, burns, broken insulation, and connectivity problems

Following that, reconnect all disconnected wires or terminals and repair any that are broken. Move to the next step should your engine fail to start despite all connections being in order.

  • Inspect The Cylinders And Gaskets

Scrutinize your gaskets to determine if they have any damage. Should you discover any issues with them, ensure you make replacements. While cylinders are difficult to inspect, compression testers make it easier to check them.

Several factors can lead to the malfunction of cylinders, including valve leakages, tear and wear of piston rings, piston holes or faulty crank seals, etc. The remedy for typical cylinder problems necessitates replacing their damaged parts. Consider running compression tests to eliminate all the potential issues.
