I've been pretty busy the last 24 hours or so with work so I just got a chance to look at that video above. I think I see where I screwed up on the carb. at 1:24 it shows how to adjust the accelerator pump arm. I was doing it wrong all along. After doing a bit more research I'm almost definitely too lean when I blip the throttle. I went the opposite way than I needed to on the arm. I think my nozzels, etc, are all sized correctly.
I'll give it a shot and try driving it when the weather clears and I have the time.
