For the sake of your all's accuracy, this is wrong (taper towards the inlet valve) -- it pushes against the inlet valve, preventing the chamber from filling with gas (that red piece of rubber is the inlet valve):

This is correct (taper towards the pump diaphragm):

There's a recess cast into the carb body that holds the wide bottom of the spring.

I finally got around to taking my carb apart. Looks like I know how to rebuild a carb after all.

My memory seems to be correct. I offered to rebuild Farrar's carb after dissembling it but he chose to let it soak overnight and rebuild it himself the next day. He made the mistake, not me.
