Good luck.
I had an experience where a well regarded mechanic shop in country town looked at my 245 with fuelling issues , adjusted it a little but problem still existed. He didnt want to go any further chasing it because,as he said,he would be wasting other customers time by fixing an old problematic car with no clear time frame. He has customers who rely on him,he is very busy and looks after European cars as well as others very well. I guess it was falling into the resto type scenario mentioned above.
Whilst I offered any amount t of cash for his time he still said no.
This I can understand, sure,wasn't happy .....
Car towed 280km to Voldat, John fixed it after some investigation.
It was the big rubber bit with a crack... hard to find.
