STARTING
OIL HOLE
4. Recoil starting
Push the decompression lever down (non-compres-
sion position, see Figure 25) and hold it while you pull
the recoil starter 2 or 3 times. (Do not start the engine.)
Electric starting
Push the decompression lever down (non-compres-
sion position, see Figure 25) and hold it. With key in
Figure 24 - Rubber Plug On Rocker Arm Cover
5. Pull the decompression lever up. Pull the recoil
starter slowly. Stop when it feels tight. This closes
the intake and exhaust valves (in compression po-
sition) and helps prevent rust from forming.
6. Wipe the oil and dirt from the engine and store in a
dry place.
SYMPTOM
No voltage when starting
generator with no electrical
load
Voltage is less than normal
voltage with no electrical
load
Voltmeter reading more than
10% high with no electrical
load
Voltmeter reading correct
with no electrical load, but
more than 10% low when
electrical load is added
POSSIBLE CAUSE(S)
1. Defective capacitor
2. Winding short circuit or loose
connections
3. Defective rotor diode
4. Loss of residual magnetism
1. Engine speed too low
2. Clogged spark arrester
3. Defective rotor diode
4. Partial short circuit in winding
5. Defective capacitor
1. Engine speed too high
1. Defective rotor diode
2. Electrical load too high
3. Engine not running properly
CORRECTIVE ACTION
1. Replace capacitor
2. Check resistance of coils (see Electri-
cal Component Specifications, page
5)
3. Replace both diodes on rotor
4. Apply 12-volt battery to capacitor
terminals for 2-3 seconds
1. Set engine speed to 3720 RPM (62
Hz) with no load
2. Clean arrester. See engine owner’s
manual
3. Replace both diodes on rotor
4. Check resistance of coils (see Electri-
cal Component Specifications, page
5)
5. Replace capacitor
1. Set engine speed to 3720 RPM (62
Hz) with no load
1. Replace both diodes on rotor
2. Do not overload generator
3. Contact an authorized engine
service center
