during my last outing just after getting up to plane the engine died. I tested for spark and nothing. I replaced the CD ignition control module and tested it. It started but seemed to be missing one one or 2 cylinders. I cant get it to run on all 3 even if I try to rev it up. It justs dies out. Could there be something else wrong that should be replaced before I ruin another Module ?

Are you absolutely certain it's an ignition problem? Could be low compression or gummy carbs. Check your spark and compression. Could be something as simple as water in your gas.
