An observation… the B&S laminations apparently form a magnetic flux loop around the coil. That piece of insulating paper in the lamination gap is “invisable” to the magnetic flux. The Eisermann lams do not form the same loop. Now how or if this difference is what’s causing the problem, I can’t answer. Only an observation.

Looking at the photo again… try testing the coil on the Eisermann lams with the assembly laying in the flywheel so that the lams and the flywheel magnet form a loop … imitating the loop on the B&S set -up

Joe, interesting thoughts on the magnetic field.
One thought I was wondering about was if the B&S coil was “polarization” sensitive
somehow. Out of my league, lol.
I’ll try the Stevens test you suggest……… maybe that will jump start some life into it!
Thanks.
