If your carb has an accelerator pump you don't need the primer plunger. 1-2 strokes on the throttle will pump fuel into the air inlet filter. If you manually pull the prop through 3-4 times before cranking, that will charge the cylinders with fuel vapor and the engine will fire right off. If you don't have an accelerator pump there isn't a quick way to get fuel into the inlet before cranking without the primer plunger.
