When preparing your snowmobile this winter, you’ll sometimes experience your snowmobile not starting.

Spark, air, and fuel are the main things that make the snowmobile engine work correctly. You should properly take care of these in order to avoid any problem in the sled.

If your snowmobile gets stuck in the snow, then this can be a big problem. So, let’s find out how to inspect a snowmobile that is not running properly. 

Some of the things which you can do when your snowmobile isn’t starting are:

Have you somehow find yourself troubled starting your snowmobile? Maybe it’s the cold or the heavy snow that caused it. Just see the best covers, ice scratchers, carbide protectors, etc., on my recommended snowmobile gear to help you get out in this stressful situation.

What To Do If a Snowmobile Doesn’t Start?

What to do if snowmobile is not starting
  1. Check the Spark

The spark will help in igniting the air/fuel mixture in order to start.

The first place which should be checked is the spark plugs. You can remove them and plug them back into the plug caps in order to test. The next step includes grounding the plug on the head bolt and turns the motor over. If there’s a spark, it is visible. You will have to change the plugs if there is a no or weak spark. The cost of spark plugs is nothing compared to the price of your snowmobile.

If there is still no spark, there can be an issue with the electrical system. Make sure to check all the electric components. All the electronic components can play a crucial role and can hence the sled to fire.

  1. Air/ Fuel Mixture

If you have a sled that has not been running for a long time, then the carbs and the gas lines can quickly dry out, thus making it difficult to start the sled. You can use the starting fluid or carb cleaner.

The engine should fire when the fuel is sprayed in the intake of the carburetor; this will help in drawing the gas with the help of the fuel system. The engine can stall after it is done running off of the starting fluid if the gas is not being drawn through.

You should do this in a restricted manner as the starting fluid won’t lubricate the engine in addition to the mixed gas or the oil injection of the motor.

The engine could become flooded if it’s over choked while trying to start it. The choke can be turned off, and the spark can be plugged out in order to fix it, it should be done until all the fuel is dissolute. Now clean the plug and put it back in.  You can drain the excess gas from the drain plugs, which are located on the end case, which is at the lower end.

If the sled floods out immediately or not getting the combustion chamber, you should clean them.

Make sure that the fuel pump, fuel lines, and filters are in excellent and working condition.

  1. Low/No Compression

The worst thing to happen is having low or no compression in one or all of the cylinders.

Enough compression should be there in order to compress the air/fuel mixture, this will, in turn, raise the mixture’s temperature and will be hence enough in order to start the combustion process.

A tester can also help you in checking the compression on the sled’s cylinder. If the compression is low, you should check it out and take the head off. The reason for low compression can be worn-out piston rings, a scored cylinder or piston, or several other reasons.

Final Words

You shouldn’t worry if your snowmobile doesn’t work. There can be several reasons for the snowmobile not working. The main reasons for engine failure can be a spark, air, and fuel. 

You can take several preventive methods before starting the snowmobile. Also, follow the safety tips whenever you go snowmobiling.

If the snowmobile doesn’t start after all the techniques, you should get the snowmobile checked from the garage nearby.
