How to change spake plug on powerlite snow blower

First disconnect the spark plug wire from the spark plug. Then use a socket wrench to remove the spark plug. Install the new spark plug into the cylinder head and reconnect the spark plug wire. The Toro CCR 3650 uses a NGK BPMR4A plug gapped to 0.032".

Have you used the snowblower recently or is this the first time. Can you explain as to different things that you have already tried. For example Checked for spark, Fuel, plastic key is there, has the outside air temperature changed?
Remove the spark plug after you try and start it and see if the spark plug is wet with gas, if so the plug maybe fouled under compression a new plug will be required. If no gas is present on the plug, there may be some ice in the carburetor from water in the gas. This is why i had asked if there was a temperature change. A trick that I tell my customers is to warm up around the carburetor with a hair dryer or heat gun. Do not get to close remember gasoline is present.

Changing the Spark Plug on an Ariens Two Stage Snow Blower

Sounds like a faulty ignition coil to me.

I would change the spark plug and be sure to gap it as per your owner's manual. I would also clean or change the air filter. I would also use only high test gas and the oil recommended by the manufacturer. good luck.
