I took my dizzy apart, fitted a oilite bush in place of the std ford crushed iron particle one, for total reliability, and whilst at it, machined off in the lathe the end of the shaft where the rotor arm sits, as I had to pull end off to grind off one of the two lobes anyway.
It now sits at the level of the metal surround ring at the base of where the dizzy cap was, made a plywood insert for here and painted black, all sealed up so water can't get in, holes in underside enlarged slightly as well.
