Random B18 engine anomalies 140-160 1968

QUOTE: "Currently yours does sound as if it's running very rich. If both the jet settings are about 12 flats down, maybe +1/-2, it sounds as if the one or maybe both of the jets are sticking down to some degree."

I've had a chance to mess with the car this morning. First off, I was operating the choke fully out way too long, essentially flooding the engine like others have mentioned. I started cold with it fully out this morning, and after about 5 seconds, was able to push it in 1/2 to 2/3rd's the way back in, and everything was fine. No black smoke or struggling.

However, I went back and started from scratch on the mixture. I tightened both jets all the way up and counted 12 flats down on each, like the above quote recommends. The car wouldn't even run under 2500 RPM, it would totally die. I kept lowering the jets. At 14-16 flats, the car would run, but would die anywhere below 2000-1500 RPM. Finally, at 18 flats each, the car will run pretty well at 1000 RPM.

I don't know if this means the car will only run rich and I have other problems, or if I've tuned it correctly now, and my jet nuts just needed more turns than others. Thoughts?
