Yeah, there are a couple "ifs", cam included...depending on which one/whose, the desired lash will be a time consuming trial & error task, it seems to be running reliably as is. I would check & record the lash as it sits, which had been set previously by somebody who should've known the specs, then tweak any stray clearances to the mean avg. At least You'll have a solid baseline to work with(see what l did there....SOLID baseline...ahahh..sigh..).
