"Cork??!!" gas cap gasket is a joke, until it disintegrates and small pieces of cork end up in your fuel tank and fuel drips all over the place. After first start of the day, re-starting when hot is "not" happening. It seems as though there is some electrical shutoff that occurs until either the engine cools or you "yank" your arm off, whichever happens first. And, this is my second Ryobi gas trimmer. My first one broke a piston rod in my second season of operation. I'm a glutton for punishment. However, fool me once... shame on you. Fool me twice, shame on me. There won't be a third time. Ryobi lost a customer for good. And, I'll tell two friends, and they'll tell two friends, and so on, and so on. Ryobi..... good luck with that.
