Paul, the connection to revving the engine may be from the vacuum vreated when
you let off the throttle. As the booster is vacuum operated, a temporary
increasein vacuum could pull the M/C a bit more.
The brake switch of my 68 LeBaron used to not be very well adjusted, right after
I replaced it (this is not pressure activated, but pedal activated). I recall,
when I revved the engine at idle w/out touching the brakes, the lights would
come on. THe reason was the increased vacuum pulled the brake pedal just a
hair. I ended up replacing the booster on this car, I do not remember if I
replaced it after or before that incident. After I readjusted the switch, the
problem was solved. I don't think this fix can be done or on the 60 year
model, of course, I just mention it because I think its interesting.
