But as I was taking the carb off to get the model #, I noticed that there is no impulse line. And when I pull up the IPL, there isn't one listed. Which made me ask, "how could it work without an impulse line?" And my next question was, "well, then, how does the carb on my lawnmower work? It doesn't have an impulse line!
So, oh wise ones, 'splain it to me, please. Are impulse lines a newer-style? Is it dependent on displacement of the engine? (a 24HP Briggs can suck enough air on its own to cause venturi effect, whereas smaller 2-cycle engines can't?) But if that's the case, it begs the question… My 3.5 HP Briggs Kool-Bore doesn't have an impulse line, but my 3.something HP Stihl MS460 does.
Help clear the carb-cleaner fumes from my brain, please! And thanks in advance!
