80 Toyota P/U 20R stalls when warmed up

I've had an on going problem for the last two years and my forehead is
getting sore from banging it against the dashboard. When my 80 Toyota
P/U with a carburated 20R warms up it starts running rough and stalls
the minute I stop. I've been through just about everything including
unhooking hoses and valves one at a time to see if it makes a
difference on top of rebuilding the carb twice. If this is a EGR
problem, is there a way to eliminate it from the system safely or a
place I can acquire one for a reasonable price? Thank you for ANY help
in this matter, Sincerely Lefty

Sounds like a choke problem on your carb.
Like the choke isn't opening as the engine warms up.
Takes the air intake cover off and watch the choke as the engine warms
up.
The choke is the flapper at the top of the carb closer to the passenger
side.
As the engine warms up the choke should go from mostly closed to mostly
open.

If it is the choke, you can either have the choke unit replaced by a
carb rebuild shop or just buy a new carburetor.

No, its not the choke. Been there done that. The choke works great, in
fact if the choke where to stay on all the time it wouldnt stall. If
you put your hand over the carb after it is warmed up and stalling the
idle will come up a stop it from stalling. Yes, I know it sounds like a
vacuum leak. I've been there and done that two. Thats why its still
doing what its doing after two years of triing everything this side of
replacing the EGR. Lefty

Does the carb have a solenoid for on the side of it?
My 79 had a broken wire going to the idle fuel solenoid, engine would run on
choke or very high idle setting but would stall if I tried to turn the idle
down below 1600 rpm. Mike

Yes it has a deceleration solenoid and the vacuum switch that engages
it is bad but, engaging the solenoid manually has no effect on it what
so ever and I did make sure it does work, the solenoid that is. Some
times it runs rough and stalls when cold but, mostly after it s warmed
up. That's why I believe it may be a EGR problem, sticking or opening
too far. Its just a real big hassle to get the thing off being its not
designed the same as most. That's why I'd like to have a second opinion
before bang knuckles. Lefty

Mine has an idle fuel solenoid, it needs power to allow gas to flow through
the idle circuit.
might be called an anti-dieseling solenoid. Mike
