Your GMX MOTORBIKES Motorized Toy Car might not be starting for several reasons, even if the starter motor is turning over. Here are a few things to check: * Make sure you have fresh fuel in the tank. * The air filter may be dirty, so clean or replace it. * The spark plug could be loose, fouled, defective, or have an incorrect gap. Ensure it is tightened, cleaned, or replaced as needed, and that the gap is correct. Also, ensure the spark plug cap is attached. * The fuel filter may be clogged, so try replacing it. * Avoid applying throttle while starting, as this can disengage the auto choke.
