Help, Installing CDI

Matt, welcome to the forum.

Well that's a new one on me. Looks pretty fancy. I've never seen one like that. Can you tell us what it is and where you got it?

Sorry I'm no help but some experts may be able to assist you.

What upgraded CDI did you buy?

The one you have is an integral unit. I've seen them before, never really messed with one though.

The concept is still the same though. The integral one just has the magneto built in to the CDI. If you get an external CDI, you must get a magneto pickup.

This goes inside the cover where your picture is showing:

This bolts somewhere on the frame:

The wiring is stupid easy. Black to black, blue to blue. There's a ring terminal on the pickup that connects to ground (one of the mounting bolts) The white wire is unused. You can wire the kill switch to both wires. When you push the button, it closes the switch and shorts the pickup out, killing the engine.

had one of those super rat CDI units here, but gave that motor away last week (wish now that I'd made a wiring diagram)

I can't recall color of the wire that gets grounded by the kill switch - google for 'super rat' or maybe new grubee has same CDI.

You have a 'Super Rat' motor!!

They use a totally different ignition system from all the other engines out there!!
Good luck finding a ignition (or any other parts for it for that matter)!
