You also have a vacuum actuator I think which controls fuel during high load, which sounds like it could be the problem - check it works by sucking the vacuum hose and watch what happens on the pump.
I can't see it, but the vacuum hose on the back of the throttle housing descends to it I think.
If you have a slack cable then that may mean the throttle isn't fully open. There should be a max throttle position screw which is missing on yours.
I'd check that all of these linkages are free and working correctly.
