I have a Mercedes 230 compact, 6 cylinder, around 1970 vintage, with a 4 speed manual gearbox.

I have recently replaced the clutch master and slave cylinders and don't seem to be able to bleed the clutch adequately. The clutch will only partially disengage and I can't put it into gear with the engine running.

Does anyone know of any tricks for clutch bleeding on this model or have any other ideas as to what is causing this problem?
