OK, lets back up. How are you testing for spark? Do you have an inline spark tester? If not, go get one from your local auto supply house ($10) and come back. You back?
On the ignition module, set the gap to the flywheel using the thickness of a clean business card. Make sure the module is on "right side" side of the module should say "cylinder". Disconnect the kill wire from the spade connector on the module. Reassemble enough to spin the motor at least 250 rpms and check for spark with your inline spark tester. Spark? If no, then you either have a bad module (likely) or a bad flywheel (rare). If yes, reconnect the kill wire and retest. Spark? If no, trace the wire back to the switch. The switch will have a cable that activates the switch and connects to the upper handle. If the cable is binding or has stretched, it will not move the switch far enough to activate. If the cable is moving less than 1/2 inch, then it is damaged and must be replaced. If the switch is moving enough, trace the wire from the switch to the module and look for open/exposed spots in the wire that may be grounding out against the engine or frame.
Good luck.

What is the coil gap

The coil makes the spark to fire the motor. A magnet in the flywheel spins past the coil to make the spark. The coil probably has some freedom of adjustment to move it close to the magnet. Not too close or it will rub. Not too far, or you will get a weak spark.

Why will the engine not start?

check the coil by the flywheel. It should be just far enough from the flywheel that you can fit a bussiness card in there. There should also be a ground wire coming off the could. When the engine is supposed to stop, the ground wire makes up and shorts the sparkplug, which stops the spark (and therefore the engine dies). I've seen these coils go bad, and I've seen that ground wire stick to something, keeping the circuit grounded.

Turns over slow, backfires , then starts.replaced battery, starter is ok. replaced plugs. what else?

If the unit runs normally after it starts it is probably a defective coil that isnt changing timing relative to crank speed. It is running advanced even at slow speeds and that is the backfire. You could also have a slightly bent flywheel key. This is what sets the primary timing so it is always a good idea to check it when you have the engine cover off!

Cub Cadet SRC 621, won't start. New spark plug, cleaned carburetor and air filter, Whiffs of smoke occasionally

Sounds like a sheer flywheel key. Common on the SRC 621. Kawasaki motor, correct. The flywheel key is under the recoil. Pull the flywheel and check the key. A very small key is there. Breaks and puts the engine out of time

I have a John Deere lawn mower with Kawasaki 9hp engine. When starting with hand rope the engine kicks back and pulls the rope out of your hand. What are the areas I need to look at? Could it be valve...

When a small engine kicks and pulls the rope out of your hands the first thing to look at is to check that the flywheel key is not damaged or sheared. This is how the ignition timing is set on small engines. If any damage to it at all, replace it. If no damage, the next thing to do is to check the valve lash gaps.

I have a John Deere riding mower Model RX75 which will not start, I replaced the spark plug and it ran just fine for one day except that it Back-fired when I shut it off it never did this in all the years...

Weak spark can be caused by a bad ignition coil. The ignition coil is located under the engine fan/shroud, next to the flywheel. Check to make sure the coil lead and plug cap are not grounding against the engine robbing your spark as well.

19-95 KLF300 ATV Kawasaki 4x4 no spark put new ignitor unit on.

You said the motor cut out and popped and backfired when it quit, this is almost always one of two things; either the low speed pulse coil or the actual CDI "black" box. You will almost never lose a main coil. One thing I would also check to make sure did not happen is shearing a flywheel mag key. When the motor backfires you can easily shear a mag key if you have a heavy flywheel, (external). However when this happens you don't usually lose spark but it will certainly cause the backfire.
One other item of importance is that the bike you are in question about does not emit a bright spark when you are checking for fire. Make sure you are using a brand new plug and ground it on the head. Try to make sure you are in a dark environment when you check the spark.
