Hi Guys, I have a CB400n that I have been restoring after picking it up from a guy who had it sitting in a paddock for ten years. I've had the bike running and revving nicely after new battery, plugs, carb rebuild etc Now for some reason the bike wont start. The starter motor turns the motor over, fuel is getting in etc. When I pull a plug out and hit the starter there is no spark. But if I rest the plug against the engine it sparks. Does this mean I have a dodgy earth somewhere? Or is it another problem? Any help would be greatly appreciate as it is driving me up the wall. Cheers. PS Sorry, I think I posted in the wrong section by mistake. If an admin could move it that would be greatly appreciated.
