Gents,
an update of the situation. I found that my new master cylinder that I replaced was also leaking, so I got a new exchange unit from my vendor who confirmed that the cups in the new MCs they have, had gone bad after some storage time.
I installed the new MC yesterday, bled the system by pedal pumping and it now works perfectly. The slave cylinder now also works fine with the new MC providing enough throw without an adapter (see pic) which I screwed on the heim joint. With the adaptor I could take away the free play by adjusting which was not necessary anymore after the new MC swap. So end conclusion: New MC was faulty, which learns me never to exclude new parts as the potential source of a problem.
Thanks to all for their advice and tips and
@jfb05177, your calculations helped and I can confirm that the stroke on the stock MC = 1,125 inch.
The throw at my slave cylinder is about 21mm
@joules: Indeed bleeding is an important element, turns out that when I used the pressure bleeder system (ronson) it didnot adequately bleed the system. The pumping by foot, albeit labor intensive, worked best for me.
reg.
