a little help will be appreciated! I don't know what are the strikethrough words?

according to the service manual

 

Adjustment feed dog follow-up movement
1. Set stitch regulator lever to maximum forward stitch length.
2. Rotate handwheel until the take-up lever has reached its highest position.
3. In this position rotate the handwheel further.
The feed dog should now advance by one tooth before it sinks below

the throat plate (with normally toothed feed dog). Fig.1.
Correct as follows:
4. Slacken screw 51. Fig. 2, page 204.
5. Rotate cam 52 as required.

6. Retighten screw 51.

Feed dog height adjustment
1. Rotate handwheel until the feed dog has reached its hi-
ghest position.
2. In this position the feed dog should be above the throat
plate by the height of one tooth. Fig. 3.
Correct as follows:
3. Slacken screw 53. Fig.4, page 204.

Feed dog lift adjustment
Please note that with the following adjustment you will not obtain the feed dog lift movement  as shown in Fig.1 but an approximately rectangular movement (Fig.2 ,page 205). The lift movement shown in Fig.2 is necessary in order to ensure that the pre-set stitch length is actually carried out by the feed dog above the throat plate
1. Rotate handwheel until the needle enters the needle hole
or the feed dog has completed its follow-up movement as
set according to page 12.
2 With the feed dog in this position it should sink vertically
below  the  throat plate when the handwheel is rotated fur
ther, and, on completion of its return journey it should
also emerge vertically from the throat plate. Please note
that this vertical lift can be only approximately obtained
by means of the round cam.
Correct as follows:
3. Slacken- screws 55. Fig. 3, page 205.
4. Rotate cam 56.
It is advisable to hold the cam by means of a tool (screw-
driver or the like) and to carry out the adjustment by
rotating the handwhneel.
5. Tighten screws 59.

why the say "Please note that with the following adjustment you will not obtain the feed dog lift movement  as shown in Fig.1 but an approximately rectangular movement (Fig.2 ,page 205). The lift movement shown in Fig.2 is necessary in order to ensure that the pre-set stitch length is actually carried out by the feed dog above the throat plate"

Isn't this kind of movement  the correct one?

Those part are the same on 168 and 68. Only the number for the various screws are different

Just so you know, the tip of the needle, feed dog and inner presser foot should reach the top of the throat plate all at the same time.  In your machine, the tip of the needle is way late.  That adjustment needs to be made.   The feed dog looks like it is coming up a little to high.  Feed dog should never rise more than the bottom of the teeth are above the top of the throat plate.
