I used the choke to shut down my ZDZ 50NG while it was at idle one time, it made the engine very hard to start the next time. I had to remove the sparkplug and prop it over to clear the raw fuel from the cylinder.
If, for any reason, you flood your engine, you can do the following to clear the engine.
Ignition OFF, Choke OFF, FULL throttle, flip it over 8 or 10 times.
Close throttle to idle, Ignition on, try to start. You may need to re-choke it.
A lot easier than pulling plugs.
