Has anyone come across an alternative firing order than 1,3,4,2, and if so why?. I have acquired a 7 Opal and it was running very sweetly, but since having the starter brushes and bearings replaced, for some peculiar reason I lost a spark to the plugs, doing the usual checks of ingition to coil and power to the dizzy, assuming the firing order to be ok I decided to fit another dizzy with the desired result of a heathy spark.
In my excitement to get her going I connected the HT leads to the appropriate plugs to fire 1,3,4,2 and checked the flywheel for TDC and when turned over had a backfire through the carb -much to the wifes alarm.I then checked whether 180% out and the carb alighted again when turned over. So hence the opening question. Any comments will be appreciated.
