Hi I have a 1961 C15 which hasn't started for over 30 years, I have purchased a new battery,coil,points,condenser, HT lead, and spark plug. I have taken a wire from the - on the battery to the - on the coil and also from the + on the coil to the points, I've also cleaned up the earth connections and taken an earth wire from the engine to the frame but when I kick the bike over I still get no spark, I don't know what else I can do as I've bypassed everything, any suggestions would be greatly appreciated,thanks
