How to Tune Up a Snowblower

January 4, 2011
« Previous Article
A quick tune-up on your snowblower is something you'll thank yourself for all winter, and this article explains snowblower tune-up steps for a Toro single stage machine. 

Getting a head start on the snow season by tuning up your snowblower is a great way to ensure that your machine will be dependable when the snow starts to fall.

For Toro single stage snowblowers, a tune-up consists of just replacing the machine's spark plug and fuel filter.

Toro Snowblower Spark Plug and Fuel Filter

This article explains the steps and required disassembly to perform a tune-up on a Toro single stage snowblower.

 

How to Replace a Toro Snowblower Fuel Filter

The fuel lines and fuel filter are located underneath the snowblower's front housing.

The control plate and control plate cover will also have to be removed for the housing to come off. 

 

1. Remove the control plate cover.

The first step in removing the control plate is to remove the control plate cover.

Remove Three Control Plate Fasteners

To remove the control plate cover, first remove the three fasteners that hold it to the control plate.

Remove the Ignition Key

Next, remove the ignition key from the control plate cover. Now the control plate cover can be lifted from its position.

2. Remove the front housing.

The front housing also holds the control plate down. And two handle bar screws hold the front cover to the machine.

Use a wrench to remove the two handle bar screws, one on each side of the snowblower.

Remove Bar Bolts

Now the front cover can be removed. It may take a little coaxing to get it away from the handle bars.

3. Carefully remove the control plate.

It's time to lift the control plate away from the snowblower, but this has to be done carefully.

The back of the snowblower's choke lever attaches to the carburetor.

Slide the Choke Lever Free

While lifting the control plate away from the machine, carefully thread the choke lever out of the carburetor.

 

4. Clamp the incoming fuel line.

Now that that control plate and front housing are off, the fuel lines and filter are accessible in the front of the snowblower.

Clamp Incoming Fuel Line

To prevent fuel from leaking out of the fuel line, clamp off the incoming fuel line to the fuel filter before removing the filter.

Clamping the fuel line can be done with hemostats, fuel line clamps, or any other clamp that will not damage the line.

5. Remove the fuel lines from both sides of the filter.

The fuel lines attach to the sides of the filter with small fuel line clamps. Use a pair of pliers to slide the small clamps aside before attempting to pull the lines off of the filter. 

Remove the Fuel Lines from Filter

Use a flat head screwdriver to push the fuel lines off of the filter. Attempting to simply pull the lines off of the filter risks breaking the lines. 

Drain the Fuel Filter

Make sure to have a small container handy when removing the old filter. Even with the incoming fuel line clamped off some fuel will most likely drain out of the filter.

6. Install the new fuel filter.

Install the new snowblower fuel filter by pressing the attachment ends of the filter into the fuel lines.

7. Replace the fuel line clamps over the filter.

Use a pair of pliers to replace the two small clamps on the sides of the filter. This will finish securing the fuel lines on the filter

Replace the Fuel Filter Clamps

To complete the fuel filter replacement, just release the clamp on the incoming fuel line.

How to Replace a Toro Snowblower Spark Plug

The disassembly from the fuel filter replacement makes it easy to finish up this snowblower tune-up. 

In fact, the only disassembly needed to access the spark plug is removal of the control plate cover.

 

1. Pull the spark plug boot.

The spark plug boot can be pulled by hand, with a pair of pliers, or with a pair of spark plug boot pullers, as pictured below.

5. Replace the spark plug boot.

6. Reassemble the machine.

Finishing up the snowblower tune-up from here just means returning all of the machine's pieces to their places. 

Remember that the choke lever needs to be threaded back into the carburetor as it is adjusted into place.

Also, keep in mind that returning that front housing to its place can be just as tricky as getting it out. 

Reinstall the Front Cover

Trying to ease the cover around all the necessary parts and back into place may take a few attempts, but a little patience will go a long way.


Make sure to replace the handle bar screws, control plate cover, the control plate cover screws, and the ignition key.
