Why is my spark plug not firing?

A spark plug won’t fire properly if its electrodes have been worn thin, if they are covered with combustion deposits or if they’re wet. If the plug has seen many hours of service, the electrodes may just be worn out, and replacing the plug will restore normal engine operation.

Why does a small engine have no spark?

A faulty ignition coil can also lead to a no-start condition. For vehicles that use a single ignition coil as the source of spark for all of the cylinders, a faulty coil will affect the operation of the entire engine.
