Air gap for coil

Assume you are asking for the air gap between the flywheel and the ignition coil?

Obtaining the correct gap from the manufacturer's specifications is best because although in theory a close gap is desirable for efficiency, flywheels grow as the engine heats up and a large flywheel can grow quite a lot.

Brass feeler gauges are best for setting air gaps as they are none-magnetic. A typical air gap would be in the region of 10 to 14 thou.

Generator will not start , no spark

Not knowing your generator my first thought would be a stuck kill switch. If not that you will need to replace the ignition module if it has solid state ignition or the points and condensor which in most cases are under the flywheel. To replace these you will need a puller to remove the flywheel and feeler gauges to set the point gap. You also need to know what the point gap is.

Check the air gap between the coil and flywheel. Also the solid state trigger in the flywheel may be faulty.

No spark - even replaced spark plug...... I'm thinking a bad magneto....??? Any thoughts or direction would be appreciated. Thx.

Most gas-powered tools of this kind use a permanent magnet flywheel and a stationary ignition coil (they call it solid state- I guess so, no liquids involved.) The ignition coils are coming from China and are of lousy or at least inconsistent quality and are frequent failures.
If you decide to replace it your self (not difficult) use a gap gauge of some kind so you can space the new coil's core the original distance from the flywheel otherwise you will end up doing it by trial and error. It will be in the range of a few thousandths of an inch.
Here is a good place to look but you will need a full model number to find the right info:

My fs55r wont start - got carb kit, new filter and sparkplur what next?

You need to make sure it is getting a nice strong spark. The electronic solid state ignition control module (coil) controls this and the contact legs on it have to be gapped about .010-.012" from the magnets on the flywheel. This goes on under the front engine cover. First, check for a nice blue spark. If it is weak or yellow, the coil needs adjustment. They fail rarely. A standard business card is about the proper thickness to produce the "air-gap" needed to create a a good spark.Also, make sure the plug has the correct gap on it.
If you have to check the coil, the front engine cover will have to be removed and moved forward to access it.Underneath the cover is the starter/recoil unit and under that is the flywheel and the coil. The coil will be attatched to the engine cylinder with a couple Torx screws about size T-15 or T-20.

Husqvarna chainsaw no spark

Ignition systems on newer saws are a solid state all-in-one package. Disconnect the kill switch wire from the ignition pack to make sure that the switch isn't broken. Use a fresh spark plug to check spark with. An old one that is black inside is likely shorted. If still no spark, replace the ignition module. Use a piece of card stock to set the flywheel magnets to module gap, then tighten screws

I need a point gap setting for a skilsaw 1616 chainsaw

Plug gap is .027 to .030
You may be able to install a solid state ignition module. It's tricky but can be done.

Tecumseh oh 140 solid state module

Check that the gap between the flywheel magnet and the module is correct, take the kill wire off the module, hook up a spark tester to the output of the module (spark plug removed), spin the flywheel - No spark means that the module is bad.
