One note on setting ignition timing: set it at 3000rpm vacuum disconnected and don't pay attention to idle timing.

The reason is because different distributors have different advance curves and at 3k rpm wrong timing can mean a melted piston or poor fuel economy/power. At idle it doesn't matter that much because it can idle at anywhere from 20 advanced to tdc and it won't do any damage.

The djet distributors use centrifugal weights for advance. If you start at TDC at idle, even at 3000rpm, max advance will be about 30deg. FSM says installation number is 7deg BTDC at idle with no vacuum.

I usually set timing at TDC at idle with vac and then rev to 1500 and then 3000 briefly without vac while checking the advance. I get max of about 27 BTDC. It's a lot easier to adjust the dizzy position at idle
