Here's another hint, in the form of a question: What do you
think the little primer button does? If you push it, and the
engine floods and gas comes out, do you think the primer is
part of the problem?

If the engine runs "as long as you keep pushing the primer
button" do you think that maybe something else is wrong?

A tiny crack or pinhole in the primer bulb will allow air to enter
instead of sucking fuel from the fuel tank.
