You have spark and fuel, that leaves compression and timing.

To test compression remove spark plug, place thumb or finger tightly over spark plug hole and pull starter cord. If your finger is pushed off the hole with pffft sound then likely compression is sufficient.

If no compression then likely a valve is stuck or a valve guide has moved out of place. Was it ran out of oil? If yes the engine rod may have snapped.

Timing will only be wrong if the flywheel key has sheared. To check timing requires a special tool or removal of the cylinder head. It's a simple flat head engine so not a difficult task to remove head and the gasket is reusable. Or just remove flywheel cover and flywheel and do a visual inspection of the key.

Safety interlock relay or safety circuit failure.

Try the following test.

Ignition in RUN position
Engine not running.
No operator in seat.
Brake ON

Press down and release the seat. You should hear the faint click/click sound of the interlock relay as seat switch opens and closes.

If you hear the interlock relay click, try repeating test with brake OFF. Results should be the same.

I couldn't with any certainty tell you there are no reed valves in the engine of your mower but reed valves tend to be fitted almost exclusively to high performance 2-stroke engines. Compressors have them and it could be argued diaphragm type carburettors have them (with a stretch of imagination).

Most ordinary duty 2-stroke engines use piston controlled ports while virtually all 4-stroke engines made in the last century use poppet valves and I strongly suspect that applies to your mower.
