We proceed with Kunen's research about existence of units (left, right, two-sided) in quasigroups with classical Bol—Moufang type identities, listed in paper Extra loops II, by F. Fenyves (1969). We consider those Bol—Moufang identities where it has not been decided yet whether a quasigroup fulfilling this identity has to possess a left or right identity. We also provide a table of all Moufang—Bol identities, indicating at each whether it describes the variety of groups, and whether it forces out the left unit or the right unit.
