I bought a 76 kawasaki kh100 the other day and have since been trying to get it running. I've skipped putting on the wiring harness and battery, since I know you can start the bike merely with the ignition coil and magneto hookups. I'm curious though- after attaching the original ignition coil wire (single black wire) to the black wire that came off the magneto (1 of 5 wires) I found I was getting a spark at the plug, which means I'm getting voltage at the coil, but no start. Is this a carb problem? Or do I just need to hookup the wire harness, get an ignition switch and do it that way (I'd prefer not to, rather just kick start) Am I connecting the ignition coil wire it to the right wire?
