And the saga continues. I rebuilt the motor, did a valve job, new fuel pump, new coil with wires, re-checked the valve gap, and still I go to take off & no power. Now I have a miss. I pulled it into the shop pulled the air filter out & ran it & it is popping a little through the carb. I also had a little wetness of gas in the airbox at the carb, and the #2 cylinder plug(driver side) is dry but black in color. I checked both plugs & they have a nice blue spark. Both plugs were brand new. About the only thing I didn't do to this so far is rebuild the carb. I took it apart & cleaned it real good, and everything looked good. Are there any certain problems with these carbs ? When I jack the wheels off the ground and put it gear the clutch engages and runs fine, but when I go to drive it there is very little power. I need to get this up & running for my little girl, and any help anyone can give me I would greatly greatly greatly appreciate.
