Expired Gas

Snow blower gas often only lasts about 90 days before losing its volatility. After that point, using the leftover gas in the machine may only generate problems, such as a failure to start.

But if the snow blower's engine can turn over, it may produce white smoke from its exhaust.

How To Fix

Drain the leftover fuel in your Troy Bilt snow blower and refill it with a fresh batch.

Follow these general steps to help you achieve these goals:

What You'll Need
  • Ratchet and socket
  • Drain pan
  • Siphon pump kit
  • Snow blower fuel
Step-By-Step Guide
  1. Place the machine on a flat and level surface.
  2. Ensure that the Troy Bilt snow blower's engine is off.
  3. Locate and remove the spark plug to prevent an accidental engine start.
  4. Place the drain pan under the machine, specifically under the fuel tank.
  5. Remove the drain plug from the gas container and let the liquid escape. Wait until the tank is empty before proceeding to the next step.
  6. Return the drain plug to its original location.
  7. Unthread and remove the snow blower's gas cap.
  8. Place one end of the hose in the siphon pump kit in the gas tank.
  9. Place the other end of the siphon hose in the gas container you bought recently.
  10. Turn on the siphon pump and wait for the gas to reach the recommended amount in the machine's tank.
  11. Remove the siphon hose from the snow blower's fuel tank and close the container.
  12. Return the spark plug.
  13. Turn on the Troy Bilt snow blower's engine and check if it still blows white smoke.

Bad Oil

Unlike fuel, engine oil typically provides the necessary lubrication to ensure the snow blower's parts don't grind. One of the downsides of engine oil for snow blowers is that it doesn't last as long as fuel for the machine.

Generally, snow blower engine oil only lasts approximately one month or up to 50 hours of operation, whichever comes first.

If you see white smoke coming from the machine, it might be a good indicator to change the oil in its engine.

How To Fix

Draining the leftover engine oil and refilling the machine with a fresh batch may help eliminate the white smoke. Here are the general steps to follow if you're dealing with this underlying issue:

What You'll Need
  • Drain pan
  • Ratchet and socket
  • Funnel
  • Engine oil
Step-By-Step Guide
  1. Put the snow blower upright and park it at a site with flat and level ground.
  2. Ensure that the machine's engine is off and remove the spark plug.
  3. Locate the oil drain line and place a drain pan next to it.
  4. Use a ratchet and socket to loosen the bolt on the drain plug.
  5. Turn the drain plug counterclockwise until you can remove it.
  6. Allow all the leftover oil in the machine to drain. Dispose of the oil properly afterward.
  7. Return and secure the drain plug to its original location.
  8. Remove the engine oil cap and set it aside temporarily.
  9. Place a funnel in the opening and pour the recommended engine oil into the container.
  10. Remove the funnel and return the engine cap.
  11. Return the spark plug and turn on the snow blower's engine.
  12. Allow the machine to idle for a few minutes to check if it no longer produces white smoke.

Warning: Don't mix engine oils. Follow the manufacturer's recommendations to choose the correct engine oil for your Troy Bilt snow blower model.

Note: You may need to tilt the machine to ensure that all the leftover oil escapes from its reservoir. If you do, return it to a position parallel to the ground before refilling its engine oil reserves.

Faulty Carburetor

A snow blower's carburetor generally provides the engine with the correct air and fuel. If this assembly wears out or acquires damages, white or blue smoke may appear from your Troy Bilt snow blower's exhaust.

Aside from the blue or white smoke, other signs of a bad carburetor include:

  • The engine fails to start or turn over
  • Your snow blower feels sluggish or has poor overall performance
  • The engine may still start or turn over, but it may take several tries before you can use the machine

How To Fix

Perhaps your Troy Bilt snow blower's carburetor needs cleaning. If so, you can watch the video below if you need help removing dirt, debris, and gunk from the machine's carburetor:

But if cleaning the carburetor didn't solve the problem, you may need to replace the worn assembly with a new unit. At this point, follow the general steps below to replace the faulty carburetor in your Troy Bilt snow-blowing unit:

What You'll Need
  • Ratchet and socket
  • Needle-nose pliers
  • Standard pliers
  • Philips screwdriver
  • Vice grip
  • Panel remover tool kit
Step-By-Step Guide
  1. Place the snow blower on a flat and level surface and ensure its engine is off.

  3. Loosen and remove the bolts securing the snow blower's front cover.
  4. Pry the fasteners from the front cover.
  5. Push the front cover up and away from the machine.
  6. Unthread and remove the screws from the carburetor assembly's cover.
  7. Squeeze a vice grip or the needle-nose pliers in the middle of the vent tube.
  8. Remove the bolts securing the vent tube and disconnect that component.
  9. Unthread and remove the bolts that secure the carburetor assembly.
  10. Detach the spring attached to the carburetor.
