Hi Ken,
Seasons Greetings from Katikati.
No doubt the New Year celebrations in Dunedin will be as great as they always are.

The book says the vacuum brake is adjusted during road testing. Leave the lock nut loose and you can turn the screw with a long flexible drive from the top left side. Screw out to induce “ping” and screw in to just eliminate it. Then tighten up the lock nut. It is all very difficult and fiddlely to get at. And hot!!!

Bear in mind that it is the left hand set of points that sets the precise moment of spark so the gap is very important.
I found it was easier to remove the distributor to work on the points.
If you don’t have the proper device to set the timing up it can be done by measurement.
Be careful choosing repro points. Most of them are crap. I have had two crack in the arms and throw out the timing.
I put a white No. 1 TDC mark on the bottom pulley and had a removable, bolt on, scale that fitted around the pulley. Then it’s easy to use a timing light like you can on almost every other make of engine.
Regards,
Terry
