My 81 B21F does the same thing. After cleaning everything and checking for leaks, I think its true that the oil is coming through the vacuum line from the flame tap.

The breather box is probably too small to do a good job of catching and returning oil to the crankcase. I have noticed that oil accumulates on the air meter plate also. This could change the balance of the plate just enough to cause a minor mixture issue also.

Perhaps installing a catch tank in that vacuum line would help.
