394xp was acting up

Seen them with a wore out throttle cable that won't let it get to full throttle....so folks try to lean them out to get the RPM's.. Create a whole new set of problems.

I saw that in one of your videos and checked it as part of my diagnosis. As mentioned above I was correct in thinking it was an ignition issue but wrong in thinking it was the coil. I should have tried the spark plug first but it was relatively new and I thought it was fine. Assumptions will bite you sometimes.
