D2 Pony Motor clutch

I have a 5j D2.I am having trouble with the pony disengaging at too low an RPM when starting my machine.I have to hold the gear lever engaged until the diesel is running properly.Where is the adjustment for this situation?

Pinion latch adjustment is inside a small cover on the side of the clutch housing near the left brake pedal. The screws are held by cotter pins. Adust a turn at a time, first one screw and then the other until you get it to hold. The latches are meshed together, so adjusting one side will help hold both of the latches in, but you still want to keep them adjusted a similar amount if you can.

You could also have serious wear or parts missing.
