How do you repair a Coleman lantern generator?

To repair a Coleman lantern generator, first ensure the lantern is cool and remove the fuel tank and mantle. Use a small wire brush or a cleaning tool to clear any debris or soot from the generator tube. Check for any cracks or damage; if found, replacement may be necessary. Reassemble the lantern, ensuring all connections are tight, and test the generator by re-fueling and igniting the lantern to see if it operates properly.
