Since your throttle wire connects directly
onto the governor control disc, you should be
alert to the fact that the nut and bolt clamping
the governor arm (in Photo 7/47) should not be
loosened or fiddled with. It takes a trained
serviceman to readjust a governor if you loosen
that bolt or the wide nut in front of the governor
control disc. So please don't fool with them
unless you get some knowledgeable help first.
Just make sure the throttle cable is lubricated
on that end. A rusty throttle cable is the most
common reason for having to put too much
pressure on the throttle lever to move it-which
ultimately leads to a bent wire and the start of
tinkering with the governor linkage.
PERIODIC LUBRICATION
Frequent lubrication of the throttle cable
works wonders. Rememberto oil the throttle ca-
ble regularly with engine oil, grease, silicone
oil spray, or graphite. All work well. Brush or
spray the lubricant on the entire length of the
cable casing. Lubricate the external moving
linkages of the throttle lever, speed control and
governor assembly.
Lubricate them at least every few times you go
out with your tiller-at least once every few
weeks. Lubrication of the throttle cable com-
ponents prior to winter storage can also be quite
helpful in the performance of your tiller in the
spring.
QUICK ENGINE MAINTENANCE REMINDERS
1. Engine Oil
- Use SE rated oi I right from the start.
-Check the oil level and make sure it is clean.
-Check the oil level with the dipstick prior to
each use of the tiller.
-Check the oil level every 2 hours, if you are
tilling all day long.
-Check the oil in the engine every 10 hours or
less.
-In dusty conditions, change the oil whenever
it becomes dirty.
2. Check and service the air cleaner frequently.
Every time you till for more than 1 hour, check
the air cleaner at intervals during tilling.
3. Clean the debris from the cooling fins on the
engine.
4. Check the governor and carburetor linkages
for operation and ease of movement. Oil them
occasionally.
5. Inspect the spark plugs.
6. Check the carburetor and air cleaner fit for
tightness and good gaskets. Make sure that
there are no movements, indicating looseness.
7. Check gasoline for presence of water.
8. Inspect the engine shroud for dents or inter-
ference with the flywheel.
9. Engine power loss (not due to faulty carbure-
tor adjustment or bad fuel):
-Check the engine compression immediately
after the engine stops running. Pull gently on
the starter rope to feel the compression.
-Where there is a loss of compression, check
for a sticky valve or valve lifter, or for loose
head bolts or a blown gasket. See an authoriz-
ed service dealer.
-Have the compression tested for suspected
worn rings.
-Worn rings can be caused by dirty oil or a
dirty air cleaner.
-Don't use non-detergent oil for long periods,
then switch to detergent oil. Use SE rated oil
right from the beginning. Prolonged use of non-
detergent oil prior to use of detergent oil can
cause excessive ring wear.
