I pulled the carbs apart today and I looked at the needle and didn't see any markings on it telling me what size it was. It also had 6 positions to place the clip when the clymer book shows that the stock one is supposed to have 5. Maybe an aftermarket needle? I have a question about the washer by the c clip. What side of the c clip does it go on?
So here's my setup and dilema: 25 Pilot jet, 340 Main jet, needle clip in the #2 position from the top out of 6, air screw 2 turns out. With the air screw 1.75 turns out, the main jet spark plug reading was rich. When I turned it 2 turns out, the plug looked perfect at W.O.T., but I checked the plugs after an 1/8th throttle run and it was wet and had a little carbon on the rim, and I had the same result for 1/2 throttle. how can I fine tune that?
