I have a Johnson 110 that had sat for several years with gas in the
carbs. I have removed and cleaned them out, and it runs great - except
for one little thing. If you don't keep sqeezing the bulb on the fuel
line, it dies. Is this a fuel pump thing, or is there anything else I
should check before diving in and rebuilding or replacing the fuel
pump?

Any advice would be greatly appreciated!
