Hi Mike,
Sorry not to have posted but been busy. If 1 and 4 are not fireing it could a bad coil (wasted spark so fires both plugs), probably loose connection of the low tension wires or bad wires from the cgi to ths coil.

got myself a meter to check ohms but need specs also not sure how to do it ,probably check input on low tension side on both coils & see if same
