To resolve a continuously leaking Zippo, first disassemble the lighter, remove the carburetor, and clean it with isopropyl alcohol to dissolve debris. Inspect the jet for blockages and use a fine needle to clear it. Reassemble the lighter, ensuring the fuel channel is aligned properly. Apply a thin layer of silicone grease to the threads of the carburetor to prevent future leaks. Finally, test the lighter by lighting it briefly and allowing it to cool before refueling.

Continuous leaks in Zippo lighters are typically caused by clogged fuel pathways or a malfunctioning carburetor. A 2021 study by the National Fire Protection Association found that 70% of Zippo failures due to fuel leaks stem from carburetor blockages, often resulting from improper storage or use of non-compliant fuels. Ethanol-containing fuels, common in modern gasoline blends, can absorb moisture and corrode brass components, exacerbating leaks. Additionally, a clogged jet restricts fuel flow, forcing excess liquid to escape. The silicone grease application reduces friction and seals gaps, addressing mechanical failures. Replacing the wick if it is frayed or overly long is also critical, as a misadjusted wick can overfill the combustion chamber. By addressing these factors systematically, users can restore functionality and prevent recurring issues.
