my cub won't start

No, spark is needed to combust the fuel in the cylinder.
Spark is created by an ignition coil sitting by the flywheel.
Those coils can go bad. Spray some carb cleaner or gas down the plug hole reinstall the spark plug, put the wire back on and try to start it.
If it pops a time or 2 you have spark.

it starts and runs as long as I spray starter fluid on the carb doesn't that mean I have spark..?? johnny
 
If the engine RUNS by itself (not relying on starter) with ether spray, yes - it has spark. You have a fuel delivery problem - carb. List your engine model #. Search the web for "engine model # carburetor"
