I think I'm on the right track now. Fied first crank yesterday and idled O.k. without stalling. The worst thing is that there are several small problems that lead to the same (or similar) symptoms and it all stems from parts that are older than dirt. They're all in fair condition but they have a lot of miles and heat cycles on them. The main issue seems solved with the choke pull-off rod adjustment (maybe a bit more fine tuning) but it's not staying on the high idle setting due to a worn step-up cam (nylon) and I don't have much faith in the choke spring either for keeping initial pressure on the choke plate. That's o.k. you guys have been great as usual for helping diagnose this little issue. Now I'll just tweak it as needed every morning until the day when I don't have to pop the hood in the morning. I can't see it taking too long.

Alright, I need to apologize to Mr. Kesteb for doubting his diagnosis of my problem. I was in denial that this situation could happen to me (mostly because it never has before) The other day I went through my morning trouble shooting regime and found the base of my carb to be coated in a thin layer of white ice after start-up. Ladies and Gentlemen, we have icing. Alright, all hair dryers aside, what is the solution to this problem. This motor probably had some kind of heat stove that ran up the side of the collector to heat the intake a little but that's long gone. Block heater is out since there are no water passages in the manifold itself. So what's the plan?

Best solution = factory solution: Go back to a thermostatic air cleaner. A working one, with heat stove and duct intact.

(And if you're looking for a new home for the existing plain air cleaner...!)

You're hilarious, is there no plan B? I really like the look of this AC. Function before fashion though, I guess.

So this was common before they had thermostatic air cleaners????????

It was more common, yes, but back then, the solution to any/every driveability issue was "MORE FUEL!" Got a hesitation, a surge, a cold-start/cold-idle issue, anything like that? Throw in more fuel! Nobody cared about emissions, and gasoline cost thirty cents the gallon. It was never the right way to address driveability issues, it was just the cheapest and easiest way of doing so. Then along came the realisation that throwing gasoline out the tailpipe is dumb, and so accurate mixture control was phased in, and that meant alternative strategies had to be devised for dealing with issues previously masked by dumping in more fuel.

Thermostatic air cleaners work a whole heck of a lot better than dumping in more fuel ever did.

I can second that!

When holley crap was on my 2.2. it RUNs MUCH better but terrible MPG and stinking up down the road and parking lot.

With weber, everything described showed up and I had to adjust closer now I have good mpg and no stink and only very small issue is little "bog" on first mile after start up. My solution was more care and roll the throttle smoother. After this first mile, all peachy.
