Engine Stalls When Accelerating (includes Pics) Sign In

I have a 84 c20 Chevy with a 305engine, Manual trans.
When I accelerate The engine seems to stutter and is hard to get up to speed unless you really compress the pedal.

I have tried the following: replaced the fuel pump and replaced the fuel filter in the quadrajet carb. I am currently trouble shooting vacuum lines, without any results. I am still double checking to make sure that I have all of the lines in the right place. Yes, there is a diagram of the vacuum lines under the hood. Any help or advise is greatly appreciated!

I have included pics of the diagram under the hood, and shots of the carb from the top and side. maybe it will help...maybe not.

Exhaust value??? bottom, behind, engine mount. passenger side

I don't see a primary choke pull off?? It also looks pretty dirty there. The choke looking plates in the back are supposed to sense lack of throttle at WOT and allow full power. With high vac they will only just crack open a bit. Vac routing and good diaphragms are a must to have right,
