I am assuming that you have the downdraft Weber. To adjust the idle
circuit you use the mixture adjusting screw on the outside of the carb
body. To adjust the progression circuit you have to set the float level
properly. To do this you have to remove the top cover of the carb, and
set the float level with the carb top held vertically. I forget the
actual settings, but I can get them from the manual if you need. The
main cirrcit is adjusted by changeing the jets. Most of the driving is
down on the progressive circuit, therefore I would check the float level,
and then set the idle mixture. When you are adjusting the idle circuit,
make sure that the car is running on the idle circuit and not on the
low end of the progressive circuit. I could get into details, but Weber
produce an excellent book, and it really helped me to understand Weber
carbs.

Using a spare bulbs with a couple of wires soldered on, check the that you
have 12V at each of the lamp assemblies. Check for bad earths at each of the
bulbs. If that does not work then, take the switch assemble off the
steering column and try to trace the wiring throught until you
find the fault.

It may be a simple case of the speedo cable needing lubrication.
