2nd Update
I’ve swapped the laminations from the old 580040 coils onto the new ones I purchased (18-5181). Here are the best directions I found on how to to the modifications to the coils and the mag plate underneath. http://www.mlaoc.ca/uploads/1/0/5/9/10597650/johnson_qd_coils.pdf
I’ll post more pictures when I pick up some replacement ignition wires. Right now I’m using the old ones and they can be routed better. But the best part is I now have spark on both cylinders! Going to have to pull the mag plate off again to secure the new wires so I haven’t tried running the motor yet.
