Buy a new one - replace it!!
Faulty/fouled spark plugs or spark plug wires. I had this problem and a set of new wires fix it.
A cylinder misfire could be from a bad spark plug, bad spark plug wire, or a bad coil. It could also be caused by a plugged or faulty fuel injector.
only way to fix a spark plug is to replace the problem plug with a new one
It should not hurt it but it will fowl the spark plug if heavy oil mix. To fix the problem drain gas out of the lawnmower and refill with good fuel and clean or replace spark plug. It will probably make smoke for a little bit but that should fix it.
no
Could be a few reasons, and can't be pinpointed without me actually seeing it "in action". But here are the most likely reasons, in order of likleyhood: 1) Spark plug not tightened to proper specs. Fix: tighen plug to proper specs with torque wrench. 2) Spark plug "washer" bad or gone. Fix: Replace washer. 3) Spark plug seals bad. Fix: Replace spark plug. 4) Bad threads in spark plug hole. Fix: Retap, or "Helicoil" it. 5) Crack in head near spark plug hole. Fix: Replace head.
no it can not start with a broken spark plug wire unless you fix it
You don't, you replace it.
Cracked spark plug bro.promise
To fix an engine with no compression first try replacing the spark plugs. Remove the spark plug wire and then remove the spark plug. Replace the plug with a new one. Reattach the wire. Replace all of your plugs and see if your engine will fire.
Misfire Faulty: spark plug, spark plug wire, ignition coil, ignition module, fuel injector are the most common. Coolant leaking into a cylinder is another. Internal engine problems such as burnt valve, broken valve spring, bent push rod, worn rings
Cylinder misfire can generally occur not only to worn ignition components like the spark plug or wire, though can also be attributed to a faulty fuel injector or a gummed injector. Certain events in a coil-on-plug(COP) design(no wires) if you find your spark plug is known-good or new and gaped properly the coil itself may be faulty/shorted. Looking further, you may have to get further diagnostics to ensure your computer system is sending proper information to the coil(all sensors working in sync).
