(1) While attaching 0.3mm thickness gauge of 1R366 to the magnet
portion of Flywheel, set Ignition coil in place.
Note: Two M4x20 Hex socket head bolts (Fig. 34) are with
threadlocker. Therefore, when re-using them,
apply ThreeBond 1342 or Loctite 242 to the threads.
(2) After setting Ignition coil, remove the thickness gauge then turn
Flywheel by hand to check if it turns smoothly
without being stuck.
Note: Be sure to insert Spacer on M4x20 Hex socket head bolt
when fastening Ignition coil to Engine. (Fig. 34)
