When you go to start it you should be pumping the pedal at least once, but usually a few times. This does two things, one it sets the choke and actuates the fast idle cam, and of course pumps some fuel into the intake to help it fire.
If you are doing that and you still need to hold the throttle to keep it from stalling it sounds like your fast idle speed and possible the choke plate need adjustment. Even if you have adjusted before, with a carb vehicle you'll need to do these adjustments a couple or more times a year depending on how dramatically your seasons change.
They are not at all going to run like a fuel injected vehicle that you can just jump in turn the key and drive off.
You'll find every carb vehicle out there has it's own personality and "special combination" to fire up easily. Once you figure out the combo for your vehicle you'll be able to jump in and get it fired right up.
Fuel/air mixture, curb idle speed and ignition timing will all need occasional adjustment throughout the year for your truck to run optimally.
