Javier,
I have a copy of the British Haynes manual and I will gladly look up whatever
I can for you.
The timing depends on the engine code but it is probably 5 BTDC with vacuum
disconnected but it could be 10 BTDC though that is for high octane gas which
you may not be able to get.
Let me know if I can help.
Incidently, I am a foreigner too but I live in the states.
