get back to the basics.

pull a plug, put it back into into the spark wire,
hold it against the head or fins, and  crank it.  see if you get spark.

if no spark, look at electrics.

if spark is present, put the plug back in, hook it up and crank it again,
pump the throttle, pull the choke out, crank it maybe 10 to 15 seconds.
pull the plug again.  if it's dry, look at the fuel system.

if it sparks, and has fuel, check compression.

fuel, compression and spark, somethings gonna happen.

look for the missing link.
