[QUOTE="Bluesnailman, post: 615322, member: 17859"] Rather than running rich, I think you might be running lean. Not lean when at idle, it at constant revs, but lean when you suddenly open the throttle. The square diaphragm mentioned above gives a squirt of fuel to deal with a sudden throttle opening and you should check out that circuit. It runs from the diaphragm along the outside casting of the carb, past a small ball bearing then up and out of the brass tube positioned above the main throttle appeture. If this isn't squirting then you will get the problem you describe. The ball bearing should be free to move in its small chamber, and is prevented from coming out by a small pin. Take bearing out and give that side of the casting a good clean, put diaphragm back in place and reassemble. Don't loose the pin or the ball bearing!! I had similar problem and this was a happy and cheap cure [/QUOTE]
