(5) Ignition Point Adjustment.
(a) Install flywheel nut on engine shaft to facilitate rotating
(b) Turn crankshaft until contact set points are open to widest
(c) Loosen screw (30) and using a feeler gage, adjust contact
set points (35) to 0.012 to 0.015 inch (0.30mm to 0.40mm).
Tighten screw (30).
(6) Ignition Timing.
NEVER reverse direction of crankshaft rotation while timing engine as bearing
clearance will result in inaccurate measurement.
(a) Install timing gage in spark plug hole (43).
Position piston in TDC position by rotating crankshaft
clockwise until dial on gage just begins to change direc-
Position the gage (in or out) of the gage holder so that a
reading of 4. 0 mm is achieved and the gage needle is at
approximately 12 oclock.
If outer gage does not read 0 zero turn outer face to
achieve 0 zero reading.
Check TDC position by rotating crankshaft clockwise.
Gage should now read 4.0mm at TDC position.
