What happens if you use the wrong spark plug in a lawn mower?

According to NGK, the world’s leading manufacturer of spark plugs, using the wrong spark plug can result in low ignitability within the cylinder. This causes the improper combustion of fuel, which can cause a reduced output of power as well as reduced fuel efficiency. Eventually, your engine will misfire.

What happens if you dont grease spark plugs?

NGK spark plugs are installed at the factory dry, without lubrication or anti-seize. Anti-seize can act as a lubricant, altering torque values up to 20 percent, increasing the risk of spark plug thread breakage and/or metal shell stretch. Thread breakage can sometimes involve removing the cylinder head for repair.

What happens if you don’t put grease on spark plugs?

Even though it isn’t necessary, putting dielectric grease on spark plugs is highly recommended as it helps keep them free of corrosion, prevents the spark from arcing, and ensures that the plug’s rubber boot doesn’t bond to the ceramic portion of the plug.

Can too much oil mess up spark plugs?

Overflowing engine oil can also lead to bent engine rods and collapsed valve pipes. Spark plug fouling – Excess oil can find its way into spark plugs, which will then need to be replaced.

What can ruin a spark plug?

Repeated overheating of the spark plug tip can cause the plug to prematurely fail. Overheating can be caused by many things like pre-ignition and a malfunctioning cooling system. Pre-ignition can lead to heat building up in the combustion chamber causing the spark plugs to fail.
