can i adjust spring onfront power valve autolite 4100

It sounds like a linkage problem. Look for an adjustment but something may be worn out. Is your choke working properly?

f-o-r thanks regarding the Autolite 4100 the carburetor works fine, the choke works fine, the accelerator works ( although the foot pedal height is almost to the floor the problem is when I press the accelerator that moves but the accelerator pump does no,t even though it's connected properly it is free and I can move it by hand and it pumps fuel into the carburetor ok and the car starts is there some way that the accelerator pump SPRING could have come loose, moved, etc I've had it off, and there doesn't seem to be an adjustment or is there? help please when it's a cold morning I have to pour fuel into the carburetor then it goes well or I manipulate the accelerator pump by hand
