My introduction and query about my '61 Apache

[Apache1309]

Greetings,
First post here, I appreciate the message boards sincerely. I recently bought a 61 Apache 235 4speed, though in need of a tune up, she ran fine. The other night as I was exiting the freeway I notice that with the clutch completely depressed at the stop sign, it died. Would restart after a couple tries, but it repeated the process every time the truck was brought to a complete stop.Thinking perhaps that the idle was off, I did some research and found that the spec idle is between 450 and 500, however, she dies out at anything below 1100. Furthermore, my truck seems to in some way require that the choke be utilized at all times for a smooth idle. I am changing out for a larger air filter today as the PO had a very tiny K&N atop the old single Rochester. Keep in mind that this is my first 235 and this is the oldest vehicle I have ever owned, that being said, some of my questions may appear novice.
I need the truck to be a daily driver ASAP, any help or tips would be greatly appreciated.
In addition, Does anyone happen to have a link to the '60 or '61 suppliment shop manuals for free download?
Gratitude!
