Cdi Box

1376 Views 3 Replies 4 Participants Last post by  polaris_arctic
Anybody know where my buddy can find a cdi box for his '76 John Deere - Cyclone 340? He had a friend working on it and it will only fire on one cylinder so they're figuring the cdi is the problem. Any other ideas to try before purchasing the cdi? I suspect they are hard to find so any help with where to get parts is appreciated.

Thanks, Classic :rolleyes:

On most snowmobiles, a single "double coil" fires BOTH plugs simultaneously. If it will fire one cylinder, the CDI box is working..Sounds more like a bad coil or plug wire...
