First, charge the battery.
You need a strong battery to:
1. Close the solenoid
2. Spin the starter
3. Engage the bendix
4. Provide voltage to the coil.
As the battery gets weaker, the first thing to fail is your spark. If the battery is almost totally dead, all you will hear is the solenoid clicking.
The more current you use to spin the starter, the less you have for the ignition.
Next, replace the plugs. If you flooded it, they're fouled & it will be it next to impossible to start. You don't need to toss them; heat the tips for a few seconds w/ a propane torch to burn off the invisible spark-robbing deposits from today's additive filled gasoline........or wash them in lacquer thinner.
While each N has its own starting sequence, none of them will start well by just yanking out the choke rod & holding it out for 5 or 10 seconds while the engine cranks. This is a gravity fuel system on a low compression engine; it is easily flooded by too much choke.
Remove the breather hose.
Get a can of starting fluid.
Key on, gas on 2 full turns, clutch in, 3/4 throttle, press the starter button. Let it crank for at least 3 - 4 seconds before you spray the starting fluid in the carb throat.
