I rebuilt, cleaned and lubricated the dizzy on my TR3A this weekend, and
it's a revelation to experience a working advance unit. The gunk and dried
grease in there was amazing.
I'm now wondering about the vacuum advance. How freely should the two
contact breaker base plates move against each other? Mine take some effort to
rotate, and I can't imagine the vacuum from the carb being enough to move
them.
Should this be a free and easy rotation, or is there supposed to be some
drag on the plates? By hooking up a tube to the vacuum input, I can get the
plates to move a hair or two (using NAFTA-sized sucking action). Should it
take
this much effort?
After resetting the valves and getting the dizzy all dolled up, I think we
may actually have a sports car in there.
TIA,
Bill Stagg
