Update
Was raining heavily here last night so never got to take her round the block.
Wife returns thursday so can measure cable travel then which I'm told should be done before driving anyway.
This is my second 911 the last one was a 79 SC and I have always struggled with adjusting the clutch.
On the SC I had to compress the omega spring and use a cable tie to hold the tension just to get the long arm & omega spring on the shaft as the heat exchanger was in the way if I didn't do this. The only other way to get it on was to lever the omega spring forward while pushing the long arm upwards onto the shaft. that method usually resulted in the screwdriver slipping off leaving some skin on the spring. On the C3 the whole gubbons just slides on, no tension in the omega spring at all, but the small arm adjuster is too far away on the only spline I can use so I then lever the long arm forwards, the omega spring rotates and it seems to be held in forward position by a very small bracket bolted to the transmission case under the omega spring. In this position the omega spring is in tension.
One of the problems I have had installing the long arm on the C3 in this way is that I seem to end up with the long arm in a different position at different times making the adjustment incorrect later in the process. I think the return problem in the pedal I have been dealing with is related to this issue and it would seem this time I have got it right. But what am I doing wrong when I get it wrong if that makes sense. I does not seem logical to me that what I am doing is so random.
The new omega spring is genuine Porsche with the correct part number from the PET and so is the new short arm I installed.
I also do not understand why the installation process is so different from the SC and the C3 either.

Carey,
Just reread your post again it sounds like using your method would remove the randomness of my method as tensioning the cable in this way is incremental rather than levering the long arm the way I have been. I wonder if I have some play that makes the long arm hang up in different positions that would explain the random positions the arm gets set in. When you use your method does this give you the required 25mm of cable travel as well?
Cheers
Bill
