I've been thinking about this all day...your gas cap can not be sealed...if it was sealed gas would never flow into your carburetor...your gas tank needs air to replace the volume of gas that is burned in the engine. If there was no way for air to get in, you would only get the gas that could overcome the vacuum created inside the tank. I guess the answer is either don't fill it up so full, or fill it up to the top, but then ride a few miles to burn the bit that will spill out the fuel vent...
