Minor tip...
I was recently asked to look at a rough-running M14 in a Yak. The cause was simple....dirty magneto points. The root cause was a poor choice of point cam lubrication grease.
Which brings us to our subject. The official Slick grease is part# M-1827. I don't know what is specified for a Bendix mag. For sure you can't just use whatever grease you might have handy.
I've been using the same grease on everything with points since the late 1970's......Bosch #5700 002 005. The notable property of Bosch point cam grease is its stickiness....it will not fly off the rotating point cam, even with engines spinning at far more RPM than a Lycoming. Nor does it melt or run.
A little plastic envelope of M-1827 is cheap enough (about a buck from several sources). The Bosch grease will be more; a 45ml tube of Bosch grease will be $7 to $17 depending on where you buy (discount import parts place vs Porsche/MB dealer). It's a lifetime supply for most of us. I just recently purchased my second tube, but I use it for a variety of things other than distributors and mags. For example, it's a good choice for clutch pivots and pilot bearings (temperature resistance), and to hold things in place (like bearings or lifters) while you assemble the parts.
Good stuff.
