well

1. it seems the "dies when shifting into drive" problem was cured by enriching the two 'CO mixture screws.' also, the book answered my question about 'uneven running' from spark plugs 1-3 and 4-6...the mixture screw on the "right" controls cylinders 1-3, and the one on the left controls cylinders 4-6.

QUESTION::: what's the likelihood of finding the perfect position for those screws shy of having a "CO measuring device" hooked up as my book suggests? Should I basically be doing a 'trial and error' on the screws until the spark plugs look good and she's running nicely? Right now, both screws are roughly 1-3/4" turns "out."

2. i've tried a number of times to set-up the correct relationship b/w the idle screw and the vacuum regulator, but my book describes it in a ridiculous way, and i have no tachometer.

QUESTION::: Anybody got a good 'down and dirty' way to get all that set nicely?

3. i've SCOURED the internet, and can't find ANYTHING that describes what the two screws i showed in this picture do. the bigger, top screw is "out" 10 turns. the smaller, lower screw is "in" all the way.

QUESTION::: If anybody has more info on what they do, or what's up with this TN Choke business MBBUFF is talkin' bout, i'd love to hear it!
