Update
Car is running EXCELLENT (motor/timing/měxture) after installing new Permatune + coil and OEM porsche shielded plug cables!
She runs SWEET!
However mechanic cleaned battery terminals and all associated connectors and figured he had fixed the non start problem.
Being sceptical I kept the old (good) battery and jumper cables in the car.
This morning cold, the car would not turn over.
I heard the fuel pump and dash lights illuminated - voltage on battery 12.4V
I parralleled the spare battery (behind the seats) and she started fine - although there was a split second hesitation.
Stopped engine immediately, detached spare battery and turned key - engine started perfectly, turning over fast and furious!
Tried it several times and could not replicate this issue.
- Joe Bob I now have the time and energy to remove the starter motor and replace or have checked (although not sure if there are any places around here who will check these out)
It is possible I have a worn bushing/bent shaft as you had?
- Or should I just fork out the bucks and get the 1.5HP starter you quoted earlier?
Is this available from our hosts or elsewhere?
Is there a brand name - maybe I can get similar more locally in Europe for speed and hassle factors.
(the French customs held up my last USA used purchase in Paris for weeks and charged around +30% to release it!)
It seems with extra 'Umph' of charged or new battery it is enough to resolve the non starting issue
Or alternatively I could backdate my 930 to twin battery!

Only kidding!
Opinions welcome
-Joebob I never disbelieved you, it was just the engine had to get 'sorted' 1st before the non start issue
Thereafter I have a huge trail of jobs to attack!
