Cool - I have acquired a twin manifold and I would like fit it  to my FC - standard 138 so should not pose any problem??

However what havens to the vacuum advance - is it split between both carbies?

Also I read on another posting "it is importatnt to make sure that both throttle openings are matched and the easiest way is with a mechanical balance shaft" what is this? Has anyone got a picy?

Thanks

Thanks guys, much appreciated - I'll try both as I have an old wheel to experiment on.

Has anyone repaired small cracks in a steering wheel - what was used for the job? Thanks.
