Clutch pedal issues on a '53 mercury

[53_mercLuke]

I am doing a clutch adjustment on my mercury and I get it so I have alittle free play so the throw out bearing doesnt stay spinning, but then my clutch pedal doesn't spring back all the way. If I tighten up the adjustment at the throw out bearing then I have no free play but the clutch pedal springs back better but not quite all the way, maybe have about 1/4" left before its sprung back all the way. Any suggestions on what I might be doing wrong or if I'm something is wrong with my clutch?
