Fuel pump question....

Ditto the previous question. Are you sure your Holley center hung float bowl is emptying in just a couple days without it leaking and leaving some evidence?
I think I'd run it a while, park it, pull the air cleaner off, pull the sight plug, and verify the bowl is full.
The next time I go to start it, I would hold the choke open and work the carb pump arm by hand, watching for the pump shot of fuel from the nozzle.

I've had a gummed-up valve hang on me, slowing the fuel shot considerably to none at all......
