Carb on a 283 v8 off idle stumble?

Hey guys my carb is a demon not sure what cfm but it runs good except for right of idle it will die unless you get past that point before it does die.. Anyone have and knowledge of this problem and how to fix it? Or should I just buy a new carb?
I have never really messed with carburetors at all so any help is really appreciated!

Thanks

Also it's pretty much stock.. Has headers but that's about it..

Well it probably your accelerator pump.
Either too much or not enough fuel to match the throttle blades movement.

That's my no eyes no ears no hands 1000 mile away guess based off of your description.

 

if its vacuum sec, they are open too fast

 

Or your timing is completely off due to a bad vacuum advance, or... a ton of things.

If it just happened then something broke, if its been ongoing, find the last part you added that caused the issue and work backward.

 

Im betting its not enough pump shot to overcome the lean condition when the throttle is opened up.

 

90% of the time

 

Install a larger # squirter, if that doesn't fix it, install a larger accelerator pump

 

I just bought the truck so I have noclue how long it's been doing it

I thought about getting a smaller carburetor for it.. But if I could get this one running smooth that'd be alot better
