| Why its hard to start engine after refueling ? |
| To match the regulations of environmental protection, the fuel Evaporative Emission Control (EEC) system is now commonly installed. Such system was set at the top of fuel tank, to perform the function to prevent fuel vapor from emission, if the driver supply too much fuel or using side stand during refueling, the fuel might backflow to EEC and choke the air cleaner, causing difficulties to start the engine. |
