Re: Chrysler 55 HP misfire

Hate to be the bearer of bad news, but if your 55 is Magna-Power II ignition, you are skunked unless it is just a bad coil. That Magna power system was trouble from the get-go and the factory offered a retro-fit unit to convert it. Parts are no longer available. You may be able to scratch up a coil but that's it, and your chances of finding a good used ignition system are almost nil.

If you are lucky enough to have a magneto system or a prestolite system (which I doubt,) Then you need to troubleshoot the points and magneto coils on the magneto system or the CD box and coils on the prestolite system.
