I messed up with my advice. Usually, you just buy the plastic bowl replacement, but that EBay deal is hard to pass up. Sorry for sounding judgy. There are many posts blindly saying to replace weed whacker, blower, chain saw carbs. Also, many times when a Honda problem comes up, a new carb is suggested without offering hardly any other advice. Speaking of carburetors, I'm working on a Weed Eater Zama carb that I can't get to work. It doesn't even get gas to the plug. When I prime it, it circulates gas from the tank through the carb and back into the tank like it's supposed to. I've watched twenty videos on "how to clean a weed whacker carb", but the meat a potatoes is just glanced over with "make sure all the passages are clear". I wish someone could tell me where the "secret" passage is on this C1U-W18 carb from the Weed Eater I'm working on. I'm severely tempted to order one even though I don't sell weed whackers I pick up...I get them running and give them away. The carb, by the way, is now soaking in "burn your skin off your hands" stuff from O'Reilly's.
