As the function of the injection nozzles greatly influences the engine performances, all the injection nozzles must be checked at every 3,000 km (2,000 miles) according to the following method.
NOTE: 1) Greatest possible care should be taken in handling the nozzles as they are the parts with high precision. 2) As the nozzle and the needle valve are in pairs, mixing up of the original combinations must be prevented by disassembling and washing one nozzle assembly after another separately. 3) Carbon deposit on the nozzle body must be removed with a piece of hard wood. However, it would be advisable not to clean the surrounding area of the nozzle orifice to avoid possible damage to the orifice. After cleaning, wash the nozzle body in clean gasoline in a container.
Removing Nozzle Holder Remove the nozzle holder following order numbered in Fig. 4-37.
CAUTION: Never assemble the nozzle needle valve and the nozzle body and slide them on each other in gasoline.
