An engine will run fine until the throttle is closed. When reopening the throttle there is a bog in the mid range. Is this the same thing as a "lean bog" condition you mention in your post?
From wat i know, if the engine rev high like starving for fuel at WOT, then after neutral position stil rev then HSN for sure is way too lean. Richen 1/8 till it idle low after wot then for sure it wont lean bog.
