The magneto air gap is a precision measurement that's taken between the edge of the flywheel and the ignition coil armature. The flywheel and the crankshaft are held together in alignment by the flywheel key.
For most small 4 cycle cylinder engines using a magneto and a coil to provide electricity to feed the spark the gap is .006 to .010.
air gap improperly set between fly wheel and magneto, bad coil, spark plug harness. Would not hurt to check the spark plug gap and ensure the connector end is tight
I believe its .020 with a magneto.
Most of the Briggs engines can be gapped simply with a business card between the flywheel and the magneto.
The magneto point gap on a 2hp Yamaha outboard is 0.35mm, or 0.014".
That would be 0.010" but a business card will suffice as as a substitute, as a matchbook could, also.

Yes, on the crankshaft there should be a "slot" called a keyway, and a matching slot on the flywheel, mate a key in the slot of the flywheel and crankshaft, and then your flywheel should be timed, also on a magneto ignition system, makesure the magneto has the proper gap, called "armature air gap" usualy if you put a buossness card in there is a good starting point
The air gap between frictional surfaces of the clutch plate and clutch rotor should be 0.40-0.50mm (0.015-0.020").
