Quick update on this one, so yesterday I cleaned up the earth connections beside the coil and from the battery to the engine hanger plate. It occurred to me that with all the new paint all over everything the engine hanger plate itself might not have been that well earthed to the frame so removed some paint under bolt heads there too. Put in recharged battery and fresh fuel and still nothing. Spark isn’t really looking very healthy so decided to wait until new battery arrives which should make a difference and in the meantime I’ve started to disconnect wires and get them identified and labeled with masking tape and try and reconnect things how they’re supposed to be - hours of colourblind fun to be had
