I agressively lean my long time since overhaul O-300 during taxi and flight and I don't have any problems with buildup/leading with 100LL. Same for the other old low compression engines I've flown.
Flyinriki - Instead of going to wherever you cut & pasted your posts, take a look at the MSDS - it lists the type of dichlorobenzene.
martymayes - the MSDS lists p-dichlorobenzene (1,4 dichlorobenzene). I'm just going with what is listed there.
