Diaphragm clutch

[Zetomagneto]

I seen to remember a few of the 750 racers used a modern clutch and saved a huge amount of rotational mass.  The flywheel can be vastly lightened
This is also on my list of things to play with.
It could give a softer clutch action.
The problem is finding a cover plate that will pass over the nose of the gearbox.

Any 750 formula racers out there.

Hi Terry, thanks for photos. Your car, and the component parts thereof are truly a credit to your engineering skills and dedication.
