Consequently, how does a gas primer bulb work?
How It Works. Pressing the primer bulb creates a vacuum that sucks gas from the fuel tank through the fuel lines and into the carburetor. Pressing the primer only a couple times should supply enough fuel to mix with air in the carburetor, and be ready for combustion.
Beside above, why does my primer bulb not work? When the primer bulb isn't working, it may be a problem with the bulb itself, with the fuel lines that feed fuel to the bulb or both. The same goes for fuel lines. When they've hardened and cracked, they let in air, which makes it impossible to draw the fuel into the carburetor properly.
Keeping this in view, do primer bulbs need to be filled with gas?
You should have fuel in the bulb when running. If you do not, the check valve in the primer is bad. It is essentially not seating and drawing air in through the discharge port.
Can you bypass primer bulb?
Removing purge/primer bulb altogether. No, it won't work depending on the engine design. Without going into details the primer bulb forces fuel to the carb jets and not the engine directly. Without the bulb your carb will be flooded on a permanent basis.
