Just replacing carb. Great stuff here. She's had it worked on recently (twice) and didn't like service so I said if anything happens I'll take care of you. So fwd. to getting air filter off and seeing a bolt stuck in carb holding flap open(man I should of took a pic)? As I twist the metal wires about and tilt carb I hear it fall and can't find it in towel I had down right there. Think hmmmmm, maybe I saw it wrong. Nope, puck up towel and there's mystery bolt. Also had wrong size o - ring on other side. Had to stop because I just can't bring myself to squeeze that o - ring in there. New one tomorrow.
