That is very interesting, lower the compression and change the timing, could work.
I think I found my misfire, I hate to admit this but my engine was loose, I have never had an engine come loose before.
I believe it could have been creating RF frequencies that could possibly have been interfering with my electronic engine cut off module.
I came to this conclusion after tightening the engine back down and flying the plane there were no misfires actually I received comments on how smooth the engine ran.

Thanks tony for that info
