Primarily before condemning an engine I suggest replacing the spark plug and also checking that you have a good spark.

Verify that all the other items are OK for example when the spark plug is removed . Turn over the engine and check for compression by feeling for air coming out of the spark plug hole.

Verify that the battery is good. If the fuse has blown it points to a likely short circuit which could be the ignition coil or a problem with the alternator but that is quite uncommon. Look for the simple things first. If you need a user guide then you can get one from ManualsLib.com or from manual owl below. Here is the link. It should have a circuit diagram which could help you diagnose where your problem is.
