I have always done a mag check (L-Both-R-Both) as part of my runup. I don't recall ever having done a mag check at idle. I did that today and i noticed that the engine runs pretty rough at idle on just the mag. I have an electronic ignition on the other side, and it idles much better on the EI (or on both). The RPM drop when i switch to just the mag at idle is also much bigger than the RPM drop during a mag check at higher power settings.
Does this sound normal?
