In my last rebuild kit there was a small o-ring seal that fit on the accelerator pump. It sat between the bowl cover gasket and the air-horn. It looked like the assembly diagram had this seal but the diagram was small and difficult to read.
in this image at the autozone site, the seal and gasket are items #20 and 21

after searching a bit, this was the only exploded diagram I could find that shows the seal
This seal, presumably kept the fuel from spilling out the hole the accelerator pump shaft pokes through on the air horn. But, it also slowed the accelerator plunger return stroke. It seemed like no problem since I don't plan on successively accelerating. But, if I did for some reason, the second time I stepped on the gas, they would not be much of a fuel shot.
Is the accelerator pump shaft seal necessary?
What if I just left this off? The last time I reset the float level, I think I did just that.
