The most likely problem is dirty contact surfaces on the brushes. Try removing the end cover on the generator. Locate the brush holder just above the bolt in the center of the rotor. Unplug the two wires to the brushes. Remove the screws on the brush holder and remove it from the generator. The brushes are spring loaded. Inspect for damage or excessive wear on the brushes. Use a piece of scotch brite to clean the contact surfaces of the brushes then spray with contact cleaner. Remove the sparkplug. Hold a piece of scotch brite against the brush contact surfaces of the slip rings of the rotor while rotating the rotor with a wrench on the end bolt. These surfaces need to be shiney bright copper. When clean spray with contact cleaner. reassemble and check output.
