Jim wrote: The early H1 uses a 12v powered CDI system. It has to be able to fire nearly 500 sparks per second (10,000 rpm), and that limits the choices. CDI units I've tested for applications like 2-stroke scooters can't make sparks that fast. You could use 3 scooter units if you used an H2 type signal generator that has three separate outputs. Maybe there's another 12v system out there somewhere that can make 500 sparks per second. As far as I remember, the test procedure you have is valid. Again, thanx. I had forgotten the early ones were DC CDI. If that makes a difference on trig polarity. cliff |

When I restored Leroy's 1970 H1 it had an ignition system form a Chrysler outboard in it. It works and you are welcome to it if you can use any of the parts. You can see it on page 5 of the restoration threads, it's in the pictures of the 1970 restoration. |

Thanks anyway. . |
