Thanks to everyone who helped me over the last couple of months. I finally have a nice bright spark on my '64 Sparta. What was the problem you ask? everything.
The last thing I did was replace the ignition coil, but I also replaced:
Spark plug cap and wire
All wiring up to wiring harness
I even took it out for a short spin around the neighbourhood, to the cheers of the kids on my street.
It was sluggish and didn't get passed 20mph, bogged down at full throttle, leaked gas from the carburetor and backfired quite a bit, but I Have Spark! WOOHOO!
