Why is my lawn mower not getting gas to the spark plug?

Clogged filters in the fuel pump More powerful mowers, such as ride-along lawn mowers, make use of fuel pumps to pump gas into the engine – instead of the gravity-feeding system that’s common in most push-along mowers. If the filters are clogged, your lawn mower won’t start because gas will not reach the spark plug.

Why are there no points in a Duraspark ignition?

With a duraspark system there are no points, as it is the function of the ignition module to disrupt the current through the coil. The advantage of electronic ignition over points is simply the speed and reliability of an electronic switch is far superior to that of a mechanical switch.

What causes spark at plug but not at coil?

If you have spark at the coil but not at the plugs, you most likely have either a bad/broken rotor, a bad distributor cap, or bad high tension wires. If you have spark at the plugs, check to make sure the distributor was timed correctly when the engine was assembled.
