I bought Coleman 200A yellow border junk item at a bargain auction. In the product description, it was treated as a junk item because it could not be ignited. In checking the problem, there was hardening / deterioration of the rubber of the filler cap of the gasoline tank and rust of the filler port. Even when pumping, no pressure was applied, and the airtightness inside the tank was not maintained. This time, I took it all apart, searched for the problem, and took countermeasures. The video has become a detailed procedure and it took a long time, but it is easier to understand the countermeasures and parts replacement procedures, so please refer to it if you like.
