You have some expensive ingition parts on that engine. I'd do some diagnosis before just replacing at random. Probably first thing to do is eliminate the control box (key switch) from the equation. Unplug the red plug harness under the cowling and jump start the starter with jumper cables. If you have spark at the plugs, you know where the problem is. If still no spark, the factory manual has a great ignition troubleshooting section. You will need a peak-reading voltmeter for some of the tests. The power pack is the most likely culprit, but you need to know if the timer base and stator are ok also.

The factory manual suggests testing the power pack output while cranking the engine over. A special meter (stevens PL-88) will test for 150 volts going from each wire going to each coil. A special shunt is required to do this test.
