Ignition modules and heating gun
I dont know if you have heard of this problem before, this is something that seems to be happening to many 912 ULS rotax engines in different airfields here.
The problem is as follows, cold starts are impossible, the propeller rotates but there is no signal of ignition, you can try forever without response. Then take a hot air gun and heat the ignition modules for 3 or 4 minutes, try again and the engine starts like a charm. As I said before I know of a good number of engines showing this behavior. Any clue?
Thanks.
