By my experience, Mighty-Vac(sp) draws air bubbles past the threads of the
open bleeder screw I have the M-Vac suction hose attached to. I was never
sure I had all the air out of the wheel cylinder I was trying to bleed. I
too have reverted back to pedal pushing.

I think you'll discover that the TD brake system doesn't lend itself
to MityVac or EziBleed. It may be a matter of its venting technique.
At least that's been my experience.
I've been quite successful using a checkvalve in a piece of tubing
connected to the bleeder valve. I put the valved end of the tubing into
a transparent container that is outside of the fender area. I then
crack open the bleeder and operate the brake pedal by means of a long
piece of wood (2x3) that I can push from behind the car. This allows me
to see the end of the tubing so that I can tell when the air bubbles/old
fluid are finished and clean fluid is coming thru. When this point is
reached you just tighten the bleeder valve and go to the next wheel.
Just be certain to not allow the master cylinder get too low. It may
sound Rube Goldbergish, but it works for me. The bleeder checkvalves
are readily available in many auto supply stores.
