RESULTS:
If sparking still does not occur after adjusting the
armature air gap, testing the ground wires and
performing the basic flywheel test, replace the
ignition magneto(s).
PROCEDURE, REPLACING MAGNETOS:
1. Follow all steps of the Major Disassembly procedures
that are located in Section 6.
2. Once the magnetos are visible, make note to how
they are connected.
note: each magneto has its own part number.
Verify the part number prior to installation.
3. Cylinder one is the back cylinder (Figure 36) and
cylinder two is the front cylinder (Figure 37).
Figure 36. Cylinder One (Back, Short)
Figure 37. Cylinder Two (Front, Long)
4. When installing new magnetos there will be one
with a short plug wire and one with a longer plug
wire (Figure 38).
Figure 38.
note: magneto gap between flywheel needs to
be 0.010 inch.
5. Long plug wire (B) will be installed on front cylinder
number two.
6. Short plug Wire (A) will be installed on back cylinder
number one.
7. Verify installation of magnetos correctly by ensuring both
spark plug wires point to the back of the enclosure and
shutdown terminals are nearest cylinder head as shown
in Figures 39 and 40.
