This method has always given a proper bleed and a good firm pedal. I believe the w123s need to be bled while using the booster and vacuum.

Hmm. you get better pedal from the ol' pump-n-flush?
I've never had any issues with 123 pedal feel after a good motive power bleed/flush session. hmmm

I did use a Motive bleeder and had my wife pump the pedal too. I didn't do it with the engine running though. Block of wood? To keep MC from going in too far maybe into rough sections of the MC?

Yes. I use a scrap of 2x4 to limit travel and my wife helps me.

Yes. Using the old pump method while the car is running has been the difference between a softer pedal that needs more pressure to stop and a harder, VERY responsive pedal.
