You bet. That's because spark plug wires aren't actually made of wire. ... That's why it pays to replace your spark plug wires before they wear out. We recommend changing them during spark plug changes (whenever your owner's manual recommends, or between 100,000 and 160,000 kilometres).

The stator coil generates the power for the spark plug and other accessories on small engines Without a stator there would be no spark at all, meaning the engine won't run. While a stator is dying, it can produce a weak spark, causing the engine to miss or run poorly. Symptoms are often worsened as the engine warms up.

*When a spark plug is referred to as a “cold plug”, it is one that transfers heat rapidly from the firing tip into the engine head, keeping the firing tip cooler. *A “hot plug” has a much slower rate of heat transfer, which keeps the firing tip hotter.

White smoke can actually be a very light shade of blue, which indicates that oil is entering the cylinders and getting burnt – see the section above for more on this. However – constant thick white smoke is usually a sign that coolant is being burnt, and you definitely don't want that to happen.

Yes, it's relatively "normal" for a charger to spark when plugging in. Not all will do it, but many high-current chargers will. You may also see a similar spark plugging in a desktop computer. ... You should be able to plug/unplug the charger in either order, or leave it plugged in while not connected to the laptop.

Spark plugs will deteriorate over time, so if they are not replaced, various engine issues will arise. When the spark plugs do not spark adequately, the combustion of the air/fuel mixture becomes incomplete leading to loss of engine power, and in the worst case scenario the engine will not run.

Use a wire brush or compressed air to clean up around the wire connections and make sure you've got a good, clean port. Replace the wires if necessary. Insert the new plugs and tighten with your ratchet. Using the spark-plug socket, remove each plug from the engine, and replace each with a new spark plug.

Causes of White Exhaust Smoke. ... One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder head, a cracked engine block, or head gasket failure caused by overheating. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine.
