How to Troubleshoot Snowblower Starting Problems

The type of snow blower you use depends largely on the conditions it will be working in. The severity of the winters in your region will have a marked effect on the type of snow blower you choose to use as well as the terrain around where you live. 

Model Types

There are three basic designs. The Two Stage Gas Blower is large and can clear an area fastest. These models have driven wheels, a snow-gathering auger and an impeller to help dispel snow. It has a clearing capacity of up to 30 inches. 

A Single Stage Gas Blower is smaller, easier to handle and relies on a rubber-tipped auger alone to gather and disperse snow. Most models have a 21 inch clearing width. 

The Electric Snow Blower has an 11-18 inch clearing width, costs less and is easiest of all to manoeuvre and store. 

Recognizing Problems

Starting problems with a snow blower generally arise from oversight or neglect of the machine’s basic maintenance requirements. Just like any other yard appliance, such as lawn tractors, lawn mowers or brush cutters, your snow blower needs to have its oil checked and changed regularly. Fuel filters will need replacing and stabilizer added to the fuel to keep it fresh and functional. Below are some steps you can take to troubleshoot starting problems and restore the smooth operation of your cold-weather friend when those snowstorms appear.   

Step 1: Choke and Throttle

Check the throttle and choke positions. When starting the engine, it is important the throttle is in the Fast position. The choke needs to be open if the engine is cold or closed if the engine is warm. 

Step 2: Carburetor Service

Make sure the engine is receiving fuel. If the fuel valve is turned off, simply turn it on. If that isn’t the problem, there may be gunk in the carburetor sediment cup. Snow blowers left sitting with untreated gas in them over the off-season often develop gummy deposits in the carburetor. 

For future reference, this problem can be avoided by adding stabilizer to the gas tank before storing away during the summer months, Allow the engine to run a while to ensure the treated gas has passed all the way through the system. You may then shut down and park. Clearing sediment out of the carburetor is a more complicated procedure and you may need the help of a qualified technician. 

Step 3: Clean the Spark Plugs

Ensure the engine is receiving a spark by establishing the spark plug is not loose or unattached. Also check for dirt. You may have to remove the spark plug, clean it and make sure the gap is correct. If that doesn’t rectify the problem, it’s possible the spark plug needs replacing. 

Step 4: Fuel Quality

The fuel in your engine may be old and unworkable, particularly if the appliance has been left unchecked over the summer months. Empty out the old fuel and replace it with fresh, top quality fuel, and don’t forget to add that all-important fuel stabilizer.
