if the nut pulls the thread on the cam all the way through. OR NOT?
at the time you bought your pulley and cam belt. kirby wiske was buying these parts from a much cheaper supplier. alot of tapers on the pulleys were not machined deep enough.
this would push your pulley forward.
i take it if you have a wider top pulley, it is the steel late ruby type. not an aluminium sports type.

Tony,
I think you are right, the taper is not cut deep enough and the pulley is slightly too far forward. But at the moment I've got it running ok with a fairly slack belt.
The wider top pulley is steel. Is this correct , on my 1934 Ruby?
Andrew.
