As you say LeSving, the manuals are great and very pilot oriented. Great figures to show you in a glance how to operate the engine.
And good info on the consequences of operating the engine on AVGAS, like 50 hr instead of 100 hr oil change, and advice on MOGAS: 1) make sure to use the right season fuel, and 2) consider the various fuel types as regards possible detonation:
Also a good forum to learn from:
Kind of funny to see on that forum that every once in a while someone pops up to suggest a different way of operating the engine in some aspect. He then (politely) gets gunned down by the excellent moderator and other experts and told to ‘just follow the manual’ 
Maybe the engine reliability statistics would even be better if all just religiously abide by the operating and maintenance instructions.

Or alternately, and at the risk of going off the Rotax topic, they could expand beyond that and not have to maintain Bing motorcycle carbs nor EFI.

You mean AVGAS 100LL. I don’t know that you need 50 hr oil changes if you run the engine on UL91 or 91/96UL.
You are right, should have been more specific.
For this generation of pilots, it‘s tough. Between about 1980 and 2010, the only Avgas out there was 100LL. Hence „Avgas“ for short. Now that we have different types of Avgas available, one has to specify. But it‘s hard getting used to it…
