I f*in hate this car.

If you have a chrome one it could have been replaced, if it loses ground or just got loose this will be a problem, it must have a tight and clean ground.
Pull a spark plug and let's see what it looks like when you have time, check for the normal things like loose wires on the coil.
When you walk out to test a few things crank it over a few times with the breather off and see if it is pushing to much gas after your fuel pump gets pressure up to the carb this can be as simple as just removing your air and full mixture adjustment screws and spaying some carb cleaner inside and then put the tuning screw back in all the way, not to tight but just bottom them out and then back them out 2 full turns.
Fowled plugs can be doing all of this, and I am sure you know that carb is doing it if not a week spark. Gap your plugs and clean them, and give this a try.
