Spark Plugs Are Critical in Running Gasoline Engines

Finding the best Honda GCV160 spark plugs is critical if you own a Honda machine powered by this small gasoline engine. Most people are not aware of the importance of the spark plug in running gasoline engines. Without a spark plug, a gasoline engine can’t run.

Supplies Spark That Ignites Air and Fuel Mixture

The spark plug is the component that supplies the spark that ignites the air and fuel mixture inside the combustion chamber of the gasoline engine. It initiates the explosion, which causes the parts of the engine to rotate and make it run.

Integral Part of the Honda GCV160

The Honda GCV160 is the gasoline engine in certain models of Honda small power equipment like lawnmowers and pressure washers. An integral part of this gasoline engine is the spark plug. Technically, it is a part of the engine’s ignition system.

Important to Choose the Right Spark Plug

It is important to install the right spark plugs to these small gasoline engines. This will ensure that the engine will start the first time you crank it. If you don’t use the right spark plugs, it will take you many tries before you can start the engine, if it could even start.

The most common reason for a non-starting gasoline engine like the Honda GCV160 is a bad spark plug. Either the spark plug is not compatible with the engine, has poor quality, or you have a damaged spark plug.

How to Determine What Kind of Spark Plug a Gasoline Engine Needs

Honda says that you can use two general types of spark plugs for its GV160 gasoline engine. The right spark plug depends on whether the engine is used to supply power to a pressure washer. To determine the right spark plug to use, follow the steps below:

  • Remove the spark plug cap and check the spark plug installed in the chamber;
  • After removing the cap, unscrew the spark plug with the use of a spark plug wrench;
  • Check the markings on the side of the spark plug, and you will see its specs. It should still have the correct spark plug gap, from 0.028 to 0.030 inches or 0.70 mm. to 0.80 mm.

When Should You Replace Your Gasoline Engine’s Spark Plug?

If the spark plug has cracks in its insulation or its electrode is already worn out or damaged, you need to replace it.

How to Install a New Spark Plug?

When installing the new spark plug, be sure that its sealing washer is right smack at the base of the threads:

  • You should screw the spark plug first with your hands carefully. This is to prevent damaging the threads by cross-threading;
  • After it is hand-tight, use the spark plug wrench to tighten it finally;
  • Tighten the plug 1/8 to 1/4 times turn after it has seated and if you have used it already; and
  • For a new plug, you should turn it 1/2 turn after you have it seated so that you are compressing the washer.

Spark Arrester or Spark Arrestor for Safety

Why Having a Spark Arrester Is Important

Since you are dealing with a combustible engine, accidental fire is quite possible as you crank it. The combustion process can emit flammable debris and light up dry grass and wood near the engine. This is where using a spark arrestor is important.

Some areas require that small gasoline engines have spark arresters to prevent the ignition of explosive atmospheres and wildland fires. To some people, they consider it an optional accessory. But if you want absolute safety, you should install a spark arrestor to your Honda GV160 lawnmower if it does not have one already.

Add as a Lawnmower Accessory

If it does not have a spark arrester, you can add it. Or, if it has one already but it has become clogged with soot, you can remove and clean it. Just remove the screws or bolts that hold the muffler cover.

Buy a Spark Arrester That Fits Inside the Muffler Cover’s Space

Buy a spark arrester that fits the size of the space inside the muffler cover. It should preferably have two holes, the size of the bolt inside the cover. Install the new arrester by using screws or bolts that fit the holes in the cover protector.

Replace the Arrester If It Has Holes

If there is already an arrester inside, unscrew it and take it out. Use a steel brush to clean out the soot and debris that clog its screen. Once it is clean, screw the arrester back again into its place. But if the arrester already has holes in it, you need to replace it.
