The video is way long but the engine sounds better, there's more power and it doesn't reek in the car anymore. All positives.
I don't think the carburetors are dumping fuel into the engine - if they are it's very subtle. I've hovered over the engine after shut down to see/smell and nothing stands out the last couple of times.
Next up after the idle fix is shortening the air filter studs and an oil change then I'll get back on the door building.
I am also going to remove the bar on the camber compensator - I think it's causing the current wheel tuck situation...removing it will let me know for sure.
