 Maybe the carbon brush isn't contacting inside, and needs to protrude a bit further..??

I had the same problem. I contacted one of the experts in OBM who rebuilds them. He sent me a new spring and carbon brush FREE OR CHARGE. I sent him half a dozen first class stamps for his trouble.

A bloke who sends half a dozen stamps out of gratitude can't be bad.
Cheers and enjoy your first karma point *smile*

Is your earth brush on the drive end OK?

The brush & spring is on the same side as the kill cable, just unscrew the large cap, it is behind it. Mind that nothing falls out ?

I'm sure that Trev means the earth brush under the screw at the mounting flange end.

Did you check BOTH brushes mentioned above? the one in the points cover cap can fall out if the cap isnt on properly. the other is under a brass screw near where the mag bolts to the engine. Both must be good.

For what it is worth, some people who don't have kill switches simply tickle the carb ( hold it down ) this will also stop the engine. Not tried it myself.

Have a nice weekend.

Earth brush is first suspect when this happens.  The earth brush is not the brush in the cap.

Is an earth brush that long?

You didn't take out the HT pickups instead, did you?
