Thank you for your question.

I am sorry you are having a problem with your snow blower. Recommend checking to make sure the key is fully inserted, if it is not the engine will not start. Then make sure the gas in the tank is fresh and the choke is turned on. If all of the requirements are met I recommend having the snow blower serviced by one of our service techs. Please call 1-800-469-4663. They will be able to instruct you on how to obtain service in your area.

I have posted more advanced checks you can do if you would like to diagnose the problem. The engine on the snow blower needs three things to run. They are fuel, spark, and compression. Please follow the steps below to help repair the snow blower.

Most of the time when a snow blower will not start it is because of old fuel or a dirty carburetor. First, go back to the spark plug. Remove the leads, or wires, that connect from the engine to the plug. Remove the spark plug wire and the spark plug. Now reattach the spark plug to the wire and hold it against the engine or another clean unpainted metal ground point. Keep your hands away from the plug so you do not get shocked. I recommend holding the spark plug with a pair of insulated pliers, and pull the starter cord. Look for sparks at the ends of the Spark Plug. Look careful as they might be hard to see in sunlight or other bright lights. If there is spark there then you have ignition, the first of the three basics. If not, you likely have an electrical problem that needs to be traced.

The engine should have been spinning over faster once the plug was removed and you should hear air rushing out of the spark plug holes in puffs. You could even try putting a thumb or finger over each plug hole to see if the pressure pushes your finger off when turning over, just be careful not to touch the grounded plugs so you do not get shocked. If that all happens then you have the second ingredient, compression. If not then you may need a valve adjustment or may have a broken component inside the engine.

That leaves fuel. Check the tips of the plug you just removed, if fuel is reaching the engine there should be some residue there and they should look somewhat wet. If you used your finger to check compression then you may even see some residue on your finger. If there is fuel here, your problem may be old fuel or a timing issue. Try putting a small amount of good fuel into the throat of the carburetor and pull the starter rope. If your problem is fuel related only, the engine should now try to start, or even run, until the fuel you put in is gone. That would indicate the fuel supply is being stopped in the fuel tank, fuel line, fuel filter, fuel pump, or carburetor. I have added an image below show how to disassemble the carburetor for cleaning.

I hope this is helpful.
