Generator will not start

I will be very interested in discovering what wsfurrie problem is, because in my case when I got my generator running again (and it started and was running again today) I knew it was not any of the following suggestions(1) low oil level, (2) carburetor varnishing, (3) defective low oil level switch, (4) open circuit coil wiring, or a (5) defective generator control assembly or voltage regulator because it has started right up and power my AC a number of times since. For two days I couldn't get the generator to run and it would run only as long as I held the switch in. The third day without changing anything I hit the start switch and it started right up and was running as smooth as silk.

ArizonaKid, where is the resistor, at the back of the switch or at the generator?
