Winter D jet tinkering, Are parts still available? Options

[robkammer]

All: Started this morning to get the BB's few quirks figured out while it's still winter. Last year the car ran great, but it had trouble staying running for the first 5 miles or so. Cold start no problems, let it sit and idle for 5 minutes, ls no problem. Once underway, as soon as I let off the pedal, it would want to stall. I was able to get through it by using the hand brake, but that's a pain.
I know I have a bad vacuum valve that is supposed to shut the throttle body down on decel, but I've just plugged it and left it place. If it's not plugged, the open vacuum takes the idle way too high. It's been like that for two years, but not for long if I can find a new one.
The AAR is working but I'm not certain about the Thermotine sender. I'm sure Jeff B or someone smarter than me has the specs to bench test one.
If anyone has suggestions on what might be the problem here, I'm open to all suggestions.
Cheers!

Does this happen even after driving for 15+ minutes when the engine is fully warmed up?
Has the timing been checked and a valve adstment been done recently?

What is the idle RPMs when cold? If you let it idle for more than 5 minutes without driving it (engine fully warmed up and the AAR is closed), will it stall, or does it only stall after you start driving it?

It may be even simpler. It may be that the idle was set while the AAR was open. Once closed, it's too low. You set the idle using the bleed screw once the car is fully warmed up (15+ minutes) and all electrical loads are on (lights {high beams, fogs, too}, heater blower, fresh air blower, etc.). FWIW, I have had best results by setting the idle higher than the spec 950 rpm, to 1000 rpm. Note this means your non-loaded idle will be higher than 1000 rpm, so you've gotta make sure your 1st gear synchro is in good shape, however, when you put it in gear at the higher idle. I always clutch and say "one thousand one" before engaging 1st. (IMG:style_emoticons/default/driving.gif)

But, as you say, that's only after you're sure of a ton of other stuff, e.g. valves adjusted, no vacuum leaks, timing and dwell, compression, etc. I'm going to write a basic tune guide, or a "before you start turning all the knobs guide" and add it to my site.
