Hello, I believe my reply from yesterday is gone forever, so I will post it again.
The fix for the car was that someone has fitted an ignition distributor from a monopoint 1.6 engine to this car. After checking the numbers on the distributor I found it was the wrong one, so I picked up a good one for the car, after fitting this one the car runs good again. The window in the hall frame was a little bit different and this caused the trouble.
Thanks to everyone who has helped me.
