This procedure solved the same problem that you describe for me.
Here is a link to the instructions:
Pages 24-25: Choke Gaps
Try this first, it should only take about 30 minutes.
As for the correct "rod" that is described in step no. 6 I just went to
my drill bit set and took a MM ruler and found a bit that was the right
diameter. I used that to adust the opening. Now on a cold start, I can
slowly or quickly push on the accelerator and there is NO hesitation or
dieing of the engine at all.
Excellent! I think my problem must be on the simple side, and hopefully just a single problem. It's as if I VERY VERY slowly accelerate I can avoid the problem, or if I just smash the gas pedal I get a b, b, brrrrrvroooom! So I can usually get past it especially once the car is warmed up.
I went out to the car after my wife fell asleep to tighten the visors, maybe try to make a speaker grill cover, and take it out for its first highway cruise. On the return, I took a video (after confirming the car was up for it). It seems like the engine is really made for high rpms. Listen to this Bee Buzz... I hit xx MPH and figured that was enough of that until I get the car checked over more carefully.
Edit: I trimmed this clip because I didn't have much to gain by showing that I can break the speed limit. All I think I need to say is that the car felt like it would have kept going to 100 if I wanted to try. When I stopped accelerating it was just because I knew that it's not wise to take a cheap car to that speed. The ride did however make me realize that this car really might be worth saving.
