Just had a thought, Bit of a long shot Brother Ron, Has an old Norton box on his Comet, His clutch was so bad, He broke a cable going to a rally. He has stronger hands than me, It moved the first bit, Not too bad Then half way it went real bad.
I was down there for something else and I had a feel of it, With my bad hands , It was unrideable !.
There is an adjustment to alter the swing of the lever inside the outer cover and I adjusted it a bit like a Vin Twin,
Bringing the bit where the cable goes as far to the filler cap as I could, = Much better, I could not think how he rode it before, I know nothing about Norton Gearboxes, Just knew I had to do something.
Cheers Bill.
