CLUTCH (CONT'D)
4_
Use a soft, blunt ended punch and hammer to turn
the clutch spider off of the crankshaft. Use one of
the two notches provided for *,,hispurpose and turn
the clutch spider clockwise, as the threads are left-
hand threads. See Figure t2. Do not pound directly
on the ends of'the spideri or clutch shoes, to turn
it. Use only the notches provided. If the spider
does not come loose after a few strokes, take the
saw to your Sears Store and let them remove the
spider. After the spider has been removed, the
clutch drum and sprocket may be removed. All _
parts should be inspected for wear, especially the
sprocket, tf it is severely worn, have it replaced, it _ i
is the most economical in the long run if the chain
and sprocket are replaced at the same time. When
reinstalling the clutch drum, apply a coat of oil to
the bearing in the clutch drum. Reinstall the spider,
counterclockwise. Just a few taps with the hammer
and punch are sufficient, as the spiderwiil tighten
itself when you start cutting wood with the saw. '

EXHAUST PORT CLEANING
Model 358-350842 (Craftsman 2.1) Model 358-350870 (Craftsman 2.1 PS)
After lengthy running time, carbon deposits will
build-up in the exhaust ports causing the engine to
lose power. The exhaust ports should be cleaned
every 25 to 30 hours. 'Pull the rubber connector
from the spark plug and remove the spark plug.
Remove the muffler. With the exhaust ports ex-
posed, pull the starter rope until the piston moves
far enough to close the exhaust port_. See Figure
!3, Use a wooden stick, about ice cream bar stick
size, to scrape the carbon deposits from the exhaust
ports. Do not use a metallic scraping tool, as you
may scratch the piston. Turn unit over and shake
out all loose carbon. If compressed air is convenient,
blow loose carbon from exhaust ports. After
cleaning the ports, pull the starter rope to allow the
piston to clear the cylinder of any material which
may have fallen into the cylinder. Clean screen with
wire brush and replace the muffler. Clean and gap.
the spark plug if necessary. Replace the spark plug
and the rubber con hector.
SPARK PLUG

If the spark plug is not clean and properly gapped,
the engine will be hard to start and will not deliver
the best performance. The spark plug should be
cleaned and gapped every 25 hours. Remove the
rubber connector on the spark plug and remove
the spark plug. Use a wire brush or a pocket knife
to clean deposits from the electrodes of the
spark plug..Be careful when removing, cleaning,
:gapping, and replacing the spark plug. If it is
damaged it will not work properly and must be
replaced. The proper gap between the spark plug
electrodes is .025_'. (use wire or flat gauge} Figure
14. After the spark plug has been cleaned and
gapped, replace it in the cylinder and attach the
