I was driving through town and spotted a couple of Harleys on the shoulder. I stop and ask what the problem is. He said it just quit and when he got it started again it wouldn't rev up. I thought about it a little bit and it occurred to me that I had heard of that problem here regarding the C14. I told him to remove the gas cap and listen for the sound of air entering the fuel tank. Sure enough, the gas cap vent was the issue. I learned it here folks and it paid off for the Harley rider. I'm just glad that I remembered the solution quickly enough. Bet he was too!
