The engine is starving for fuel, that is why it will keep running while you force the fuel to the engine with the primer button. At this point, the carb will have to be removed,disassembled and cleaned. I'm sure you will find blockage and dirt in the carb and also in the small orifices for air and fuel flow.

some toro primer bulbs don't fill up with fuel but blow air into a chamber in the carb that has fuel in it so when you press the bulb, the air sprays fuel into the carb ( just a little) So since it won't start, the bulb probably has a very small crack in it. replace it and then try it.

The carburetor may need to be serviced. You need to find a parts shop that handles Tecumseh parts. You will most likely need a rebuild kit for the carburetor. The carburetor part number is 640303. The rebuild kit is 632809. The Tecumseh engine company shut its' doors 3 years ago. Finding parts is becoming harder and harder. I've heard that someone has bought Tecumseh over the winter but it is unknown when the new parts will hit the market. Best of luck to you.
