first
50 hour break-in period, then inspected every 250 hours
thereafter and replaced as needed.
A WARNING: Do not remove the spark plugs while
the engine is hot. Allow the engine to cool before
removing them.
Spark plug gap: 0.031 - ± 0.0002 in. (0.8 - 0.05 mm).
Spark plug torque: 10 -15Ib·ft (1.5 - 2.31 kg.m).

--CHECK FOR
DETERIORATION
AND DAMAGE
The choke solenoid is a 12 volt DC operated unit that func-
tions to close the choke plate in the carburetor when the ON
switch is depressed during engine start-up.
The choke solenoid de-energises once the engine starts and
the
ON switch is released. Some unstable running may be
present when the engine starts cold,
but should smooth out as
the engine reaches normal operating temperature.
Keep this solenoid dry and periodically lubricate the linkage,
plunger and choke
shaft with graphite lube.

DRIVE BELT ADJUSTMENT
The drive belt must be properly tensioned. Excessive drive
belt tension can cause rapid wear of the belt and reduce the
service life
of the fresh water pumps bearing. A slack belt or
the presence of oil on the belt can cause belt slipping.
1. Remove the belt guard.
2. To release the belt, back off the pivot bolt and loosen the
bracket bolt.
3. Swing the bracket to loosen for removal.
4. Inspect the belt for frayed edges and excessive wear.
S. Re-install
or replace the belt and re-tighten the bolts.
The drive belts are properly adjusted
if it can be deflected
no less than 3/8 inch (lOmm) and no more than 112 inch
(12mm) as the belt is depressed with the thumb at the
midpoint between the two pulleys on the longest span
of
the belt.
NOTE: Maintain a 22 Ib pressure to the belts outer face for
proper belt operation. Spare belts should always be carried
on board.
A WARNING: Never attempt to check 01 adjust a
drive belt's tension while the engine is in operation.
6. Operate the generator for about 5 minutes, then shut down
the generator and recheck the belt(s) tension.
7. Replace the belt guard.
