Air-flow mass meters were not on a 1966 Benz, more like 76. It is an early K-jectronic, obviously.

C180MB, please present your facts more accurately as we can be of more accurate assistance.

The little air cleaner? is that the one on the injection pump you are reffering to?
I am not so familiar with this system yet and i haven´t found a service manual yet.
Actually i don´t know where the cold start valve is either, i have searched in the owners manual but haven´t found much.

Yes, on the pump, actually on the warm-running device. It screws in and there may be a nut that tightens against the housing to hold it.

The cold start valve is on the right side near the fender. It has a fuel line (pressurized) and a wire for the solenoid.

As a general guide, the Haynes manual, #63020 (230, 250, 280) works pretty well.
