This issue is often intermittent, making it difficult to diagnose until the coil is tested or replaced. If you're experiencing this problem with an Inca lawn mower, checking the ignition coil would be a good starting point.

Remove the kill wire from the ignition coil. It's the only wire that doesn't go to a plug. Remove one of the spark plugs. Reconnect the plug wire to the plug that has been removed. Make sure the threads of the plug are touching metal on the engine somewhere. Crank the engine. Should see spark. If not, bad coil.
