Place a teaspoon of gas in plug hole and see if it fires up (no choke) for a short burst.

Did it run before?

Any performance parts? Valve lash set right? Timing marks on cam and crank lined up? Good flywheel key? Electronic or points ignition? When in doubt buy a new spark plug.

Not cranking is not the same thing as not running. Sorry, it just annoys me and can lead to confusion...

Clean the carb, possibly replace the diaphragm. Check the pickup tubes when you have the carb off the tank. Could be cracked/broken off/clogged with debris.

the marks are lined up with each other touching, its firing , its all stock, carb on gas tank, what is valve lash? maybe it could not let it crank>

Will it start for even a moment on starter fluid or can you not get it to attempt to run? I am seeing a sort of confusion here. We understand it will not stay running.

Please elaborate.

Valve lash is how much play you have in between the cam and tappets when the valves are shut, if you didn't mess with the valves this wont be a problem. Also make sure you don't have a sticking valve.

Its firing? So i assume its not staying running. It is back firing? And is it points or electronic ignition? If its firing but wont stay running, it sounds like carb issue, if it backfires then valve issue
