Feed dog timing should be adjusted so that the top of the feed dog teeth are level with the needle plate when the eye of the needle descends into the hole of the plate. The feed timing adjustment on your machine is a cam on the main upper shaft.
To adjust the feed timing set the needle eye so that it is just going into the needle plate hole. Then loosen the set screw slightly and turn the cam to have the top of the teeth just go below the level of the plate. Tighten the screw and test.Note that when you advance or retard the feed timing you will also increase or reduce the maximum stitch length. The picture below is of a different machine, but very similar and I have marked with a yellow arrow the set screw that you need to loosen. Set the stitch length during this adjustment at midway so as to get the slide out of the way of the cam.

Cathy,
Thanks for the diagnosis and what to adjust.
When I worked on this before I tried to move that cam. I couldn't get it to budge. Is this the only screw for that cam? If I remember right (questionable at 12:15AM) there are two screws. When I had them broke loose the last time I didn't know what to use as a reference point. Thanks, I do now. What is the best way to turn that cam? Will try this tomorrow and get back with you.

Cathy,
Studied this critter this afternoon. I can't adjust it via the cam. There is a longer lock screw 180º from the one you told me to loosen. The second screw locks the cam to the main shaft going to the head. It actually passes through the counter weight looking part, into the cam. The other screw you told me to adjust looks like it would lock the short hand wheel end to the cam. But if I change that it doesn't move the feed dogs just the other vertical shaft that drives the oscillating hook.
Also when I ran the needle down into the needle plate as you instructed, just as the bottom of the eye entered the plate the feed dogs were just a hair over the top of the plate and only at the rear of the dogs. So I'm not sure that what little movement of the cam it would take to move the dogs would clear the stitch adjuster part.
Sent you a PM earlier. Will now await your reply.
Sigh, such a pretty machine to be so out of sorts. Perhaps an attitude adjustment is in order . Bwahahahahaha .....
