the image shows the vcr after repair.
the original problem was that the tape was not being pulled into position for the pinch roller to drive it.
the tape was dropping down from the cassette behind the guide pin that bring the tape forward to the pinch roller.
the cam gear (white gear#1) was in the wrong position
to resolve this...
first, be careful to note the position of all gears. (take a picture)
remove the circle clip on the black (drive gear#2)
remove this gear, the white cam gear can now be rotated
rotate the white gear until the guide pin (under blue dot) is centred in the cam gear's slot (red arrow)
now, the tape will drop down from the cassette in front of the guide pin.
