The purge bulb (more commonly called the primer bulb) manually pumps fuel into the carburetor, which purges the air out of the carburetor. Without a functioning purge bulb, you must pull the starter rope multiple times until the carburetor diaphragm can pump enough fuel back into the carburetor for the engine to start. That is the reason, if you do not like them, just delete it. But why?I didn't say it was a Walmart saw. What I don't understand is why they need a primer, or purge, bulb. They went out in the late 60's when Tillotson started becoming THE carb. A properly functioning HS Tilly shouldn't have needed more than 3 or 4 pulls to start. Ever since Husky bought the Poulan line I've seen more and more Poulan in their lower end saws. Don't get me wrong, older Poulans are fine saws. I own a few, but they didn't need primer bulbs either. I sold a lot of 266/181/2100's back in the 80's and knew Husky then as a really pro saw. Maybe someone can enlighten me as to why the "purge" bulb is needed? Some odd EPA idea maybe? I can't see them holding up any longer in the woods than they do on a weed whacker or Walmart Poulan.
And yes, I am ignorant which is why I'm asking the question.
