[TR] Ignition question (and hello!)

[Malcolm]

Thanks Geo.  I tried the rotor again tonight and it does return back,
although it's not snappy like I would hope.

I also ran the car with the timing light and saw that it is floating a bit
at idle.  I've got new points to try, and I'll replace the coil, but I
foresee a rebuild in my future.
