Reply To: This sound like it needs a tuneup?

Well shoot. Something is wrong and I can’t fix it right now.

Did a tune up, hooked up some Atom modules I have had on the shelf for a long while. Ran rough still. That’s fine, bottom cylinder is cold and nothing changes when I pull the plug wire, I pulled the flywheel and swap the polarity of the wires on the module as you sometimes have to do.
Start it up, again and it runs even worse. Pulling the plug on the bottom cylinder again does nothing.

Time for a compression test or something, I guess. Dadgummit.
