What is the right spark plug and gap for my small engine?

What is the right spark plug and gap for my small engine? Checking and changing spark plugs is an essential step in routine small engine maintenance and when troubleshooting problems with your lawn mower, snow blower or other outdoor power equipment.

What causes a spark plug gap on a lawn mower?

Gaps can get misadjusted by dropping the spark plug on its ground electrode, by engine heat causing the ground electrode to slightly move or by constant use eating away part of the ground electrode. When the anode gets thinner, the gap is increased.

What kind of spark plugs do I need for a lawn mower?

Flathead Engine Spark Plugs & Gaps. Also known as L head or Side Valve Engines, these engines are commonly used for walk behind lawn mowers and pressure washers. If you have a Quantum engine, be sure to check the Code Date before doing any engine maintenance.

What is the pressure between the spark plug gap and ground electrode?

between the spark plug gap (center electrode and ground electrode). 2) Pressure in the combustion chamber at time of spark discharge – Depends on compression and aspiration of the engine. High compression engines and engines with forced induction have higher combustion chamber pressures at time of spark discharge.
