I finally removed and replaced the accelerator pumps on our 2800, the symptoms were sluggish response at lower RPMs when accelerating. In all it took maybe 30 minutes tops. It was no surprise that I found the original pumps with their unique leather skirts were still present. I bought new pumps from Carl Nelson.
You first remove the air cleaner and the center mounting stud. There are eight screws around the perimeter, keep them in order as two are slightly longer. Then remove the smaller screw under the mounting stud.
Next remove the small set screw from the rod controlling the choke plate.
Carefully lift off the cover and the pump is now visible, located under the lever that actuates it. Remove the screw that holds the lever and gently pry its post outwards to remove the lever.
Lift up the pump, insert your new one and button it back up, pretty simple.
