Many thanks for your advice so far.
I will check the timing in the next few day when I get myself a timing light.
It´s a 1999 PEUGEOT 103 II Vogue we built last year for a friends 40. birthday. That´s why it´s called APOLLO 40 :-) We chose the Vogue because of its standard 12V CDI system and the very low mileage.
I keep you updated..
