The local Rotax rep showed similar damage (from the same source) to the same
parts during a presentation to the Europa Squadron in southern California.
I doesn't matter if it's an aviation engine or an automobile engine, lead
fouls everything it gets near.

Martin,
Nigel Beale, who sells the Rotax engines here in th UK, has shown me a head
and valves from a 912 which used 100LL. Both were heavily contaminated with
yellow lead deposites to the extent that the valves could not operate
properly. I forget how many hours the engine had done but it is something
you should be aware of. The engine was designed to operated on unleaded
Mogas.
If you e mail him at skydrive@avnet.co.uk he could probably enlarge upon
this.
Dave
