Thanks for the helpful hints folks! I found the issue after dissecting the transformer and discovered the "A" post wire to the throttle terminal had broken off. I was able to solder it back on.
My next question...I noticed that the secondary coil has some "wiggle" room and hangs pretty close to the primary coil. I vaguely remember someone telling me that it would be problematic if they touch etc...
So, I was able to stick a thin piece of plastic at the top of the metal "core" and underneath the secondary coil which raises it slightly. (Pictures are attached).
I have not tried to operate it yet (because I am waiting on some parts to be delivered), but was wondering if what I did is safe?
As always, thank you in advance for your wonderful insight!
