There are some items I have read about that do present problems. More piston engine problems than rotary. 100 LL is really a misnomer, there is a large amount of lead in 100LL compared to say old leaded auto fuels. One of the problems listed was a "washdown" effect caused by the typee of use aircraft engines usually get. Hard use 80-100% followed by long periods of non use. Lead buildup caused problems on valve stems, plug fouling, etc. Of course the fact unmentioned was that the high lead levels in 100LL cause some valve sticking and plug fouling when used with petroleum based oils as well. Run your engine regularly and you should have few problems.
