High Pmag RPM drop?

[tkatc]

At idle my checklists suggests to lean until I achieve a fuel flow of 2.5 gallons per hour. (idle is somewhere between 8-900 RPMs) When you throttle up to taxi it should run fine but if it wants to stall...you have it leaned too much. Leaning on the ground with EI and FI is important so as not to foul plugs.

I have two pmags installed on an O-360, carb and fixed pitch Sensenich. I had a 100 rpm mag drop on the right mag and 40-50 on the left. Brad suggested I check all the wires for security. I found that a couple of wire in each mag had loosened up. I turned the screws at least a half turn or more on most of the connectors. This solved my problem, both mags 40-50 mag drop at 1400 rpm and leaned for altitude. Also pull the 6 wire connector and reset and insure the two screws are tight on both mags. Dan.
