For easy removal of Rod 2.5 from Rocker arm,
position Piston at compression top dead center as
follows:
Remove Spark plug and then insert 1R411
1
through the spark plug hole.
Turn Flywheel [1] until Piston reaches the
2
highest position. (Turn Pulley [2] instead of
Flywheel [1] if the blower body is assembled to
the backpack frame.)
Turn Flywheel [1] (or Pulley [2]) 45 degrees left
3
and right to confirm the position of Piston.
If Valve does not move, Piston is positioned at
4
compression top dead center. If Valve moves,
Piston is positioned at exhaust top dead center.
In this case, bring Piston to compression top
dead center by turning Flywheel [1] (or Pulley
[2]) 360 degrees.
This method to find compression top dead center can
be applied to our all 4-stroke engines.
