I have an intermittent problem that is getting annoying. I thought I had a fouled plug issue as my right mag is horrible in the run up area especially after the mechanics do run up testing (was theorizing they were full rich and fouling the plugs). After several minutes of running lean attempting to burn it off, it has cleared twice recently.
This past weekend I gave up, was taxiing back, and tested it again and miracle of miracles, it was smooth. Mag drop was HUGE this weekend, like it wasn't there HUGE, then a backfire. A buddy indicated check mag as well as ignition switch (which they are).
My question: How do you test a mag as a mechanic? Is there some type of equipment or bench test? I don't want to just haul off and change it, only to find I still have the same issue after new install.
