Let's assume that you're airborne and notice (via your engine monitor) that one of your cylinders is not firing on one of your mags/EI. I had this scenario happen once when I had a fouled plug. The mag run-up was fine before take-off, but I guess the plug fouled after the run-up (I had an extended hold after doing my runup). In my case I detected the issue by noticing several anomalies on my engine monitor (higher FF, #2 peaking before #3, etc). I did an in-flight mag check and sure enough it was running rough on one mag.
Anyway...what is the correct procedure in this situation? Should you continue to fly off of both mags or just the non-offending mag?
