When you say the cruise control comes on I assume you mean the cruise on light illuminates but the 'Set' light doesn't. There's another switch involved with the cruise control, it's the throttle shut off switch. It's located down by the carbs where the throttle cables attach. All told counting the clutch switch, front brake switch, rear brake switch and the throttle switch there are four switches that have to work properly for the cruise to be set. If all those are working right then the problem could be in the wiring to the ECU which is the brains of the outfit. I don't think a broken vacuum line or bad vacuum control solenoids would cause this problem. If it was caused by those two failures I believe the 'Set' light would still light up even though the cruise control would still fail to work.
