1984 Chevy hard to start

Whenever the truck sits overnight it is difficult to start. I pump it a few times and it will run for about a half a second and die. I have to repeat this a few times before I can give it some gas with out it stalling. After about ten seconds it will idle on its own. Any thoughts? I also have a hesitation when taking off and I have to give it gas slowly. If I floor it, it doesn't go anywhere. Related problems? I'm worried I won't get it started when it gets really cold. I had this same problem in the summer as well.

first check for vacume leaks

if none found make sure the choke linkage is free moving not gummed up and that it sets when you pump it

if this all is ok get a carb rebuild kit and new float and filter most likly the accelerator pump is shot and a freshening up is all thats needed

Definetly sounds like a choke problem. I have an edelbrock 600cfm carb w/ manual choke truck doesn't like to go unless its warmed up.

Had the same problem with a Ford powered by a 4.9L. Trying to pull the boat out of the water was cute. I had the carb rebuilt, and that took of the problem for about twelve months.
 
I agree with everyone who says "carb rebuild." I had the same problem with the Quadrajet on my 1986 C-20 crew cab w/the 350 "M" engine.

As a side note, Q-jets often leak from (up to) 6 pressed in plugs on the bottom of the carburetor. When rebuilding, mix up some fuel-resistent epoxy and smear the plugs to ensure a leak-proof assembly.
