Hi
I have Bendix mags on an 0-320 b2b and on the left mag I'm getting a 200+ rpm mag drop when I do a mag check. I did a search on here and read a bunch of things it might be .
I changed the plugs that go to that mag one at a time,no luck,I even got brave and while it was idling I pulled the plug wires off each plug from that mag one at a time and there was a NICE spark that was jumping across from the wire to the plug when I pulled each one, plus I could hear an RPM drop as I pulled them and an RPM increase when I put them back.
I checked the timing with buzz box, it was out a couple degrees so I set it back to 25 degree same as the right mag. Still didn't help . So I pulled the mag looked at the points and checked them to see and they were .018 gap.Cleaned things up reinstalled and still the same .
Any more thoughts??
THANKS
