How to adjust the floating chamber valves
When having dismounted the carbs (just dismount them, you donīt have to separate them),
remove the floating chamber cover. Using a gauge, measure
the distance between the upper edge of the float and the edge of the floating chamber,
with the valve closed. The distance has to be 7 mm. If
itīs not, adjust the distance by carefullyand slightly bending the float.
