a broken spark plug der
no it can not start with a broken spark plug wire unless you fix it
Broken spark plug wires will keep almost any car from starting.
Why would you want to put a broken spark plug back in your lawnmower? Get a new one!
Buy a cheap ice pick. Using a vise or good pliers, bend it at the end at a 90 degree angle or so to make a hook. It should be strong enough to get the rock out. Otherwise pull the spark plug boot off, break the ceramic plug part, remove all broken fragments of rock and ceramic, then unscrew the rest of the broken plug and install a new plug.
Yes. that plug will need replaced.
The best tool - would be a pair of small tweezers. That would probably help you remove the piece stuck in the socket.
Oil on the outside of the spark plug is normally a sign of a leaking valve cover gasket. Oil on the spark plug electrode, (plug must be removed to see this oil), is normally a sign of a broken or worn piston ring. A compression test will verify if a ring is worn or broken.
I do not understand why you want to remove the porcelain if it is broken off. Just remove & replace the spark plug which is no longer any good if the porcelain is broken.
Could be bad spark plug, spark plug coil, mismatched spark plug wire, or loose/broken motor mounts, or problem with head gasket.
Pull on it, its just stuck.
bad spark plug wires, low battery, broken rotor in the distributor
