Thank you John and Jim for your replies.
The carb was rebuilt around about 4 years ago and the spindle is actually still very good.
I also "discovered" the hidden jet underneath some years prior to that when I owned my first Ruby
and couldn't work out why the mixture screw was so unresponsive and I think it was actually someone
on the forum who pointed me in the right direction in that instance.
Although I never actually remove the jet for fear of damaging it, I always manage to keep it clear
either by the use of fuse wire or/and the use of the air blower on my compressor.
So in response to your very kind suggestions, I'm afraid I have already ruled out the actual carb's
various jets and am in the process of checking for any leaks on the manifolds,etc.
It's certainly a puzzle, but what else is there to do on such a gloriously hot day than to spend it
with your head under the bonnet?!
Thanks again.
Graham
