Wow, I haven't seen that type of system since the 70's!!!! CR Chuck Voboril <[EMAIL PROTECTED]> wrote: Chris, I looked at a pick-up (exciter/pulser assembly) and also a flywheel and the flywheel has 4 magnets. There is just one pickup on the stator fixed to the crankcase. The manual wiring diagram and theory of operation (pg 2-26 Ignition System Theory of operation) backs this up.
Each pair of magnets that follow each other are for the charging and triggering of the CDI circuit during a 180 rotation. At the same 1/2 rotation, the other 2 magnets are charging when they go by the ends of the lighting coil. So the same set of 4 magnets do TRIPLE duty as an alternator, CDI charger, and CDI triggers. Thanks for your ideas. I had forgotten all the details myself of how this worked. I think he may actually have a broken rod which explains the internal ker-thunk every rotation along with the the mashed ground electrode. Just pulling a carb and rubber mount or exhaust manifold should allow a look to see little or no movement of the piston on that side.
