by the ignition system or the valves, therefore, determine the caus$ of the trouble before attempting to adjust the carburetor. O Foreign particles in the fuel often enter the carburetor and cause the malfunction of the engine by restricting fuel flow. Visit your Honda dealer and have your carburetor serviced every 3.000 km (1,860 milesi.
