Richard, IMO -carbs may not be the problem. An old rule which I try to follow
is "Carbs last -- after everything else is eliminated". The reason we go for
the carbs first is because they sit right there looking at us (and with those
big air cleaners!). SU's and ZS's are simple devices really and are not prone
to just "go out."
Check your ignition system (points, condensor, coil etc.) and the other parts
of the fuel system (pump, linkages etc.) before monkeying with the carbs
themselves. Please let us know what you found after you find it. Cheers.
