4-14. OFF-SEASON STORAGE
If the machine is to be inoperative for a period long­
er than 30 days, the following precautions are recom­
mended;
Step 1. Working outdoors, drain all fuel from the
fuel tank. Use a clean dry cloth to absorb
the small amount of fuel remaining in the
tank, then run the engine until all fuel in
carburetor is exliausted.
|W\RNIN^
DO NOT DRAIN FUEL WHILE SMOKING
OR IF NEAR AN OPEN FIRE.
4-13. MAGNETO AND SPARK PLUG CHECK
WHENEVER CHECKING THE MAGNETO
OR THE SPARK PLUG FOR AN ELECTRI­
CAL SPAR.K, USE INSULATED PLIERS TO
HOLD THE SPARK PLUG WIRE OR THE
SPARK PLUG,
a. Magneto Check
Step 1. Disconnect the spark plug wire from the
spark plug, and place throttle control lever in
CHOKE or FAST position.
Step 2. Drain all the oil from the crankcase (this
should be done after the engine has been
operated
and is still warm) and refill the
crankcase with clean new oil.
Step 3. Disconnect the spark plug wire and remove
the spark plug from the cylinder. Pour
about six drops of engine oil into the cylin­
der, and then pull the recoil starter several
times to spread the oil on the cylinder wall.
Replace the spark plug, but DO NOT con­
nect the wire.
Step 4. Clean the engine and the entire tiller thor­
oughly.
Step 5. Lubricate the gear cane an indicated in par­
agraph 4-2.
Step 6. Wipe tines with oiled rag to prevent rust.
Step 2. Using insulated pliers, hold the wire close
('/4-inch distance) to engine block or cylin­
der, then crank the engine several times. A
spark
should jump from the wire to the
block or cylinder; if a spark does not occur,
check the wire and the magneto.
b. Spark Plug Check
Step 1. Remove spark plug from cylinder but leave
the wire connected, and set throttle at
CHOKE or FAST position.
Step 2. Using insulated pliers, hold the metal side
of the spark plug in contact with the engine
block, and crank the engine several times.
The
spark should jump the gap between
the center and side electrode in the plug.
Step 3. If a spark does not occur, check the elec­
trode gap and repeat step 2. If no spark
occurs, replace the plug.
