Norm, you should invest in a 'gap type' spark tester. They're inexpensive and available online or at your local auto parts store. This is the easiest way to determine if you have a coil problem(or other electrical problem like kill switch issues). The engine manufacturers typically don't provide specs on things like coil resistance, etc. Nowadays, with components molded into the ignition 'module', you can't necessarily get pure DC resistance measurements, like you can when you are dealing with a just a magneto coil only.
Using the tester, you can see immediately see if you have spark or not. This is one of the fastest ways to determine if your problem is electrical(ignition) or fuel related.
As 30YT mentioned, when you have a chance you should post the engine info and we can provide more targeted feedback. Good luck!
