I did the other Eisemann to OMC coil swap today. I wish I had a better way
to machine down the width of the laminations, other than angle grinder, belt
sander, 5″ round sanding disc in the drill, Dremmel, and big fat flat bastard file.
Would that operation be something a milling machine would excel at?
I have not check for spark of this latest coil swap yet, but going by results of the first,
I’m very hopeful! I have a few loose ends, terminal ends for
the plug wires, adjust the points to .018, and figure out what to do for new spark plugs.
The KD4 had J8J Champion plugs in it, which the manual says is correct.
Of course, they’re a good 1/4″ shorter than the modern J8C Champions.
I have not tried to determine how much clearance the later plug would have, if any,
with the plug covers bolted on the engine.
What are any of you running for modern plugs in these engines?
Thanks!
Prepare to be boarded!
