It sounds like you are reading the RPM, not the dwell angle off your meter.

As for the point gap, I looked it up on the CD, and they don't give a gap, only a dwell angle of 47 degrees.

You adjust the dwell angle by changing the point gap - by turning the distributor you are changing the timing. I suggest that you get the dwell right, and then set the timing with a timing light. The CD says 10 degrees BTDC.

Carbon on the plugs means you have a rich fuel mixture. It could be from several causes. I would get the gap and timing sorted out, then take the car for a drive that allows it to get fully warmed up. Then pull a plug or two and see what the carbon situation is.

If you need the dwell and timing procedure, send me an email.
