Just a shot in the dark here,but have you tried replacing the sparkplug wire, or done a compression check?

Sounds like my 85hp Chrysler. If your cyl. is not getting spark try checking the resistance of the trigger unit. Mine drops #3 intermittently. I havent cured mine yet but it seems to be the trigger. I have switched everything and still #3 gets no spark. I tugged on the wires going to the trigger and it started running on all 3. You might try that too.

Thanks to all! The plug wire is apart of the coil and can't be replaced. Today I was going to compression test it, however my earlyer thumb over the plug hole seamed to have compression even thou I just turned the flywheel by hand.<br />Yes I have moved the trigger wires when running and no change, also did a resistance test and that was fine.??????<br />Any more suggestions?

Imagine everything back as it was. The CD wire feeding #1, is to be assumed to malfunction. Now on the 2 CDs you have 3 wires are left.Those 3 wires are to power your 3 cylinders. You had a CD wire that was useable but not employed because its there for a 4th cylinder.

I did do a compression check and all 3 cyl. are 120lb. I went ahead and puued the stator and trigger everything looks OK ??????

Have you tested for spark at all 3 cyls.?
