I snapped this pipe this morning while i was hitting the starter moter. Just wonder if it is anything important that i should replace, or whether my quick duck tape fix should be ok? There was no fluid in it.

Thats a vac pipe.
Controls your mixture for the carb from the dissy. It nees to be replaced and have a good seal.

I think it is attached to the throttle lever, to pull it closed when you take your foot off the pedal (if that makes any sence). It was like it when i bought the car. I always thought it looked a bit bodge.

yeah, my weber doesn't have one of those, I think it has one of those buterfly springs on the pawl rather than that, i suppose if it works, its not a problem.........

its the vacuum advance pipe. its advances the ignition timing via vac suction from inlet manifold. its should be replaced but better off blocking pipe off until it can be repaired permently because if its not air tight it will weaken the fuel mixture.
hope this helps. kev
