one more thing . you did a very good job on your post. you explained exactly what was going on . that makes it a lot easier to help diagnose from an armchair .ive seen posts like {car starts and dies } what should i do?fwiw

77cruiser:
Sounds like the pulloff needs some tuning, adjust it so it doesn't open the choke so much on startup.

Cliff Ruggles:
Problems on initial start up are pull-off related, not how tight you wind the choke in the housing.  As long as it's completely closing the flap, the choke setting is for how long it stays on, nothing to do with how it works at initial start-up.

I use and recommend the E-choke conversion, much better set-up than the factory hot-air, those systems leak are excellent only when all the components involved are in perfect working order.....Cliff

vickleford:
Got the old pull-off out and played with it to figure it out...

Then went to the Blazer and adjusted it to where it just barely opens the choke when I push the pull-off all the way in, put the air cleaner back on, closed the hood, and it fired right up and stayed running in the 27 degree snow.

Welp, I'm just about happy enough to do a backflip. Instead, I'll open a beer. Here's to 429bbf, 77cruiser, and Cliff!  Thank y'all very much. I am one seriously happy camper.

429bbf, thanks for your kind words too!

Cliff Ruggles:
Good news, think I'll have a beer as well, after work today that is!......Cliff
