(5).
3. Put the specific tool (7) through the fork lever hole of cylinder
block (9) and hook the start spring (6).
4. Keep this spring slightly extended and install the injection pump
(4). Make sure the control rod (8) should be pushed by the idling
adjusting spring (1) and the pin (5) on the rod engages with the
fork lever (2).
5. Hook the start spring (6) to the bracket (3) using the specific tool
(7).
6. Hook the governor springs (small and large) (14) to the
governor lever (13) using the specific tool (7) and install the
speed control plate (11). Be sure to place the copper washers
underneath two screws (12) in the upper of the speed control
plate.
7. Install the engine stop solenoid rod (15) to the guide hole of
cylinder block (10) and fix the engine stop solenoid (16) with
socket head screws.
NOTE
• Be careful not to stretch the start spring (6) too long.
Otherwise it may get deformed permanently.
• Make sure the start spring (6) is tight on the bracket (3).
• The sealant is applied to both sides of the soft metal gasket
shim. The liquid gasket is not required for assembling.
• Addition or reduction of shim (0.05 mm, 0.002 in.) delays or
advances the injection timing by approx. 0.009 rad (0.5 °).
• In disassembling and replacing, be sure to use the same
number of new gasket shims with the same thickness.
