A point gap of 22 is a bit wide. I try to aim for 20.

You can't trust the Nu-Rex timing wrench the first time you use it. After setting the point gap correctly, you have to use a test light (a 6 volt bulb with test leads) or an ohmmeter to set the initial timing correctly (with the spark lever fully up).

AFTER you set the initial timing with a light and tighten the cam screw down, taking out all slack by gently turning the cam clockwise, you can see where the Nu-Rex wrench falls on the distributor body relative to Pin #4 on top.

I find many cases of the wrench going 3/8" or more PAST pin #4 when the timing is right. It is not because of a manufacturing error by Nu-Rex. This is due to the position of the cam follower on the modern points being in the wrong position on the breaker plate, compared to where it is with stock points. (A good reason to stick with original points.)

After all the work you've done, this engine should be running by now. You have overlooked one small thing.
