The left carb drips a little gas from the overflow tube when it's running. It doesn't drip when the engine's off and the gas is on. I've taken the carb off about 6 times and I can't find anything wrong. I've tried different needles and set the float from 21 to 26 mm with no effect. The carb is in good shape and everything is clean. It started after I changed jets and it's got me stumped.

 

sounds like you need a new float

 

should have road it on new years would have made a good boom... lol j/k

try putting silicone around the outside gasket edge...
