Doesn't CFI have to have and instrument rating to teach
instrument flight?

Depends on which definition of instrument flight you want to
consider.

1. Control and maneuvering of an airplane solely by reference
to instruments.

2. Instrument flight training

Item 1. being that training required for the Private Pilot
certificate and need not be given by the holder of a Flight
Instructor-Instrument/Airplane certificate.

Item 2. is that training required for an Instrument Rating
and must be given by the holder of a Flight Instructor-Inst-
rument/Airplane certificate.



Section 61.195: Flight instructor limitations and qualifications
(c) Instrument Rating. A flight instructor who provides instrument
flight training for the issuance of an instrument rating or a type
rating not limited to VFR must hold an instrument rating on his or
her flight instructor certificate and pilot certificate that is
appropriate to the category and class of aircraft in which
instrument training is being provided.
