I see you have new plugs, but are you getting spark?

Take off the outer filter cover on one side and try spraying a bit of starting fluid on the foam filter.
Then hit the starter button.

This simple test may help you discover whether you are missing spark or fuel.

If there is no stator output and the battery is dead, it will not run. The ignition system has to get power from somewhere. It will start and run with jumper cables connected to another battery, but will die as soon as you disconnect them.

not nessisarily true Jerry. as long as the battery has at least 11 volts it will still run, or if the stator puts out a least 10.5 volts it will continue to run. it won't run well, but run none the less.
