how do i know i need a new spark plug for my snowblowerIf your snow blower is not running very well it could be because you have a bad spark plug. It could also be due to bad fuel, a dirty carburetor, or even a clogged filter. The only way to really tell how I know I need a new spark plug for my snowblower is to check. A poorly running engine is just the first symptom. Either you or a mechanic will need to eliminate the possibilities until you have a smooth-running engine. Here is some more information about checking your spark plug.

How do I know I need a new spark plug for my snowblower

The easiest first step is to actually check the spark plug. If the engine will run, but not smoothly, then you already know that the plug is delivering a spark to the combustion chamber. If it will not run you will need to ensure that electricity is being delivered.

Remove the spark plug after first disengaging the spark plug wire. If the spark plug is dirty and coated with deposits either replace it with a new one or clean the existing one. If the porcelain around the central post is cracked or chipped, replace the plug. Otherwise, it can probably be cleaned with sandpaper.

After all of the deposits are removed, set the gap to the recommended gap provided in your manual. Reattach the spark plug wire and ground the outer electrode of the spark plug against the housing. Turn the engine over once or twice by pulling the starter chord. You should see a spark between the central post and the outer housing. If not you may not be getting any electricity to the plug.

Once you have confirmed that there is electricity being delivered, re-install the spark plug and try starting the engine following the normal procedure. If it will still not start, remove the plug to see if gasoline is being delivered to the combustion chamber. You should be able to smell it. If not, you will need to clean the filters and possibly the carburetor.

If the spark plug is wet, you may have flooded the engine. Wait a few minutes and try again.
