We're having a little trouble deciphering this. We speak English here, more or less.

Anyway, try shutting off the fuel supply (remove vacuum from petcock, or pinch off fuel supply line). Just because you're getting fuel doesn't mean you're getting atomized fuel.

Now, from there, with intake filter(s) in place & intact, spray some ether into the inlet area of the airbox. No need to go overboard.

If your engine has compression and spark, and you spray ether into the airbox, it almost has to start. It's almost in defiance of the laws of physics in not starting.

Try the above with a good running bump start, to crank the engine at a reasonable speed for several seconds. When (not if) it returns to life, repeat a few times and then restore the fuel supply.
