I have a Kawasaki FC420V HS09 engine with no spark. New coil ( 211212086) coil air gap and new spark plug gap good. Resistance readings of the coil seem ok although I cannot find a spec sheet on the coil. Coil kill wire disconnected from the coil. Engine doesnt have or parts diagram show an ignitor module. Flywheel magnet seems powerful enough. I dont know what to do!! Please help!!!

1, How are you checking for spark?
2, Try flipping the coil over, if installed the wrong way it will not fire at the Correct time and not start.

tried the flip and I hold the plug against the cylinder and use a spark light tester

Coil gap at .012" (pretty much spot on for a business card) i would try cleaning up the mounting posts where the coil sits with some sandpaper...
Like you I didn't see a igniter module in the IPL...
Also, try a new spark plug. I had to help my brother over the phone the other day with a honda generator... sparked looked OK out of the plug hole, reinstall it, no start, even with starting fluid, put in a New NGK gapped at .030" and it fired right up. sometimes a weak/bad plug will not spark in the cylinder.

Try leaving the kill wire unplugged from the kill terminal of the coil. If the engine you wil lneed to choke it to death or shut the fuel off somehow to kill the engine.

Then it must be a defective coil as it should fire; unless, voltage had been applied to kill terminal as it is designed to only grounded to kill.

that one slipped me... voltage coming in on the kill wire is a good way for a coil to get toasted quick.

Saving money on Crinese parts normally costs you more headaches than the OEM part would of.
