I think nearly all interference was caused by car ignition systems which
would have been positive going, but modern cars don't use distributors
any more so the biggest source of interference has gone anyway.
Was the dizzy more of a source than the plugs themselves?
I would have guessed so as the plugs themselves were totally enclosed at
the point of spark whereas the distributor normally had to spark across
from the rotor to the cap about four times a revolution. Plastic is
not a good shield for radio frequencies.
