We love talking to our customers whether you know what’s going on with your small gas engine or you’d rather just leave the details to us. But we like to empower customers with knowledge to boost their confidence when you talk to us, as well as to reassure you that we’re the right shop for your small motor needs. We think that spark plugs are fascinating little bits of technology, which is why we’ve chosen the mighty spark plug to examine with you this month.

Just like the plug on your floor lamp, a spark plug is a conductor for electricity. It needs a power source at one and fuel at the other to play it’s part. When you start your lawnmower this sends an electrical current through one end of the spark plug which turns into a spark at the other end. The spark plug has a centre electrode running through the middle, (aren’t mechanics excellent at naming things?), that carries the current, and a grounding electrode on the side to pinpoint the location of the spark. Once the spark ignites the fuel, the force of the blast kicks your motor into gear. The steps are the repeated until you turn off the machine.

The spark plug is commonly connected to the starter system through the spark plug wire. Whenever you’re working on your small combustion engine machine (e.g. lawnmower, snow blower, leaf blower, etc.), you’re always instructed Sparkplugsto disconnect the spark plug. Often, what you’re really doing is disconnecting the spark plug wire from the spark plug, the plug itself stays in place. This step is crucial for your safety so don’t skip it, even if you’re just cleaning out grass clippings.

If you’re experienced and planning to check the status of your spark plug, always use a torque wrench and dial it to the strength specified by the manufacturer. Tightening the spark plug too much can result in stripped threading, and a broken plug altogether. Don’t Hulk SMASH, okay? When replacing a spark plug you don’t need to shell out top dollar. A high-performing spark plug can help to maintain fuel efficiency and get your engine revving on the first try, and by “high performing” we mean one that’s designed to complement that specific motor, not necessarily one labelled premium.

The spark plug needs to be replaced when there is a visible buildup of deposits of carbon or oil on the tip. This gunk gets in the way of the electrical charge coming through the spark plug wire to the fuel and can be the source of an abundance of issues. Uneven wear can also be a sign that the spark plug needs to be replaced. It’s like trying to light a match on a worn out striking surface; not enough power. It’s okay if the spark plug is discoloured because, well, fire. But if it’s damaged at all, out it goes. Trying to clean the plug isn’t worth the damage you may cause; a brand new one is inexpensive and worth the peace of mind.
