It's pretty important, Keith. Basically - the pupose of the vacuum line is to
advance or retard the ignition timing in accord with the air pressure at the
carb intake. That pressure changes depending on speed and
acceleration/deceleration. In effect the line keeps the carbs and the
ignition in synch. This insures that the spark jumps the gap in the spark
plug at the optimum moment in the combustion cycle. Cheers.
