Just have someone crank it over - and hold your finger over the inlet side and try to feel some suction. Make sure you plug the other side when you disconnect it or the fuel will run out of the tank. Be careful with electric drop lights and heaters etc. Or disconnect from the carb and run a LONGER piece of hose to a bucket -- see if it pumps. These are dual action pumps - suck and blow. LOL
Invest 12 bucks and get a service manual. Try "Books4Cars" -- search on google -- they're local here and have manuals and all manor of stuff for cars. Reasonable.
