  If your KTM Offroad Vehicle's engine turns over but doesn't start, there are several potential causes and solutions: * **Operating Error**: Make sure to follow the correct engine starting procedure. * **Old Fuel**: If the vehicle has been sitting for a while, the fuel in the float chamber may be old. In this case, empty the carburetor float chamber. * **Fuel Feed Interrupted**: Check the tank breather, clean the fuel tap and clean the carburetor. * **Engine Flooded**: Clean and dry the spark plug, replacing it if necessary. * **Spark Plug Issues**: If the spark plug is oily or wet, clean and dry it, replacing it if needed.
