Hello, my brother in Australia has just bought himself a Motobecane Mini Moby 1978 and is in the process of doing it up. He cannot find anyone with tech. information about the bike. He needs to know "what spark plugs and ohms readings to test the ignition coil". I cant find anything on the net (in English anyway). Can anyone help me (us) with the answer or a point in the right direction? Thank you in advance.
