I do love the sound of a sub normal idle on the ground but would trade that anyway for a clean power band from 1/3 to WOT...
True... as long as the engine does not fail me in the air, I do not really care how it runs on the ground, and by now, I think I have a fair feeling of what an engine that does a good job in the air sounds like while on the ground.

My gutfeeling is that it was intended for cam lubrication, but it could very well be of influence on the mixture distribution as well.
But it depends on how the engine was intended to be mounted, since twins usually have an "up" and a "down"...
