Well...swapped the coil over for one i had sitting on my plentiful spares shelf

and no difference. Poked about a bit with a multimeter, pretending i knew what i was doing. Didnt find anything i could make any comment about. Thought i would have a look at my fuel filter and decided to take it off as i have never been happy with the way it sat and also thought it wasnt flowing enough fuel coz it was never full up with petrol
Anyway, lo and behold she fired up on all 4

however.............she did cut out a few times and i think i may have a loose connection somewhere.

as during all of this i checked a plug to see if it was sparking...and it wasnt
Will have another poke around tomoz if i can.
