maybe this afternoon it will fire up in anger
This CCM came with a Runtronic ignition so we will see how it goes.
In the world of ”real” engines, the RUNTRONIC system can bring new life into old machines. Take a vintage racing motorcycle, for instance: what a relief to get rid of the whole complicated and touchy magneto! Where flywheel magnetos are used, they can be replaced by a much lighter impulse generator (a disc with a magnet) plus a RUNTRONIC ignition module. You will get easier starting, better acceleration, more power and much improved reliability. For high speed two-cycle engines, that require reduced advance at the highest speeds, the advance curve can be tailored to a specific engine and a specific application.
If you are building your own SI engines, you will find the RUNTRONIC system to be an easy-to-use, bolt-on unit, that will breathe sparkling life into your creation.
The Runtronic spark ignition system is provided with an electronic advance and retard circuit for rpm controlled ignition timing. The system generates three sparks in two degrees of crankshaft rotation up to 4000rpm and then single spark thereafter which makes the engine easy to hand start. The engine will not kick-back, since the ignition point is automatically retarded at start.
No mechanical advance and retard device is needed. Total advance and retard range is up to 30 degrees stepless variable.
