Snowmobile Engine Startup Troubles

You have your gear on, your plans made, and you are ready for a snowmobile adventure. But when you turn the key, ready to hear the roar of the engine, you hear nothing. Or maybe it’s an anemic grind, an annoying click. Regardless of the sound (or lack thereof) your snowmobile makes, one thing is sure. You won’t be going anywhere until you take care of the problem.

There can be any number of reasons why your snowmobile might not be starting up. Some are simple to overcome, and others might require more investment. But first, you have to determine the cause.

Troubleshooting a Non-starting Snowmobile

  1. SnowmobileGot gas? If this is the first ride of the season, it might be you forgot you emptied the gas tank at the end of last season. Check the tank. The situation could also be that gas was left in the tank, but you forgot to add stabilizers, so the gas deteriorated during the off-season.  If so, empty the tank and replace it with more gas. Heading down the trail might be as simple as adding some gas.
  2. Is it on? Sounds silly, but if you forget to flip the switch On, your snowmobile won’t start. Flip the switch and proceed on your adventure.
  3. What about the battery? Snowmobile batteries self-discharge if not used often. So, those dormant months are the perfect scenario for your battery to weaken. Pull out the charger and be patient.
  4. No Sparks. It may be that the spark plugs have worn out. This is one of the most common reasons a snowmobile won’t start. As the spark plugs engage the engine to burn the fuel, you will need to replace them if they have worn out.
  5. Oil and filters need replacing. Your car isn’t the only vehicle requiring occasional oil and filter changes. This is an easy fix. Just grab the filter and oil you purchased from your AMSOIL dealer, The House of Syn, and make the changes.
  6. Are the fuel lines blocked? To check for this, you must remove the shroud covering the motor. Inspect the fuel lines and fuel primer. If these are blocked or damaged, they will need replacing before you can ride.
  7. The clutch and carburetor have dried up. The carburetor’s job is to mix the gasoline with air based on a specific ratio. If you are already on the trail but heading high in the hills, it may be that the colder air has affected its efficiency. You will need to adjust the settings to allow for more fuel than air. However, don’t make this adjustment without first checking the owner’s manual.
  8. There is damage to the gasket case. This is due to worn-out piston rings, a bad crank or reed valve, or a damaged head gasket. A simple solution is to try tightening the head nuts first. But if this isn’t the case, you will need to postpone your riding plans and do some mechanical repairs. These are common problems but ignoring them is not an option.

Once you have determined why your snowmobile isn’t starting up, you are halfway on your adventure. Be sure to keep some AMSOIL products on hand to keep your snowmobile ready to go. Then suit up and get ready to ride!
