Default Re: Who Can Diagnose THIS Total Mystery? Win A Prize?

I would agree with Jim, Try another gas cap. I suspect your vent is partially blocked. The gas goes out slightly faster than the air comes in and creates a low pressure/vacuum in side the gas tank. The choke is simply cutting the air flow and creating a richer mixture for a short while and allows you to go another hundred yards or so.
