Hey Alan,
Horizon finally replaced my ICU-L ignition. The original caused "dead-stick" and rough running problems. It looks like that if your can't change the timing, it is defective. I almost lost a $700 plane because of the ignition. It is running a lot better and no "dead-sticks". It should run even better when broken-in. Are you still flying your Evolution 58 and how is it doing? Here is a short video with new ignition:
