alternative in minimizing the formation of fuel gum
deposits during storage. Add stabilizer to gasoline in
fuel tank or storage container. Always follow mix ratio
found on stabilizer container. Run engine at least 10
minutes after adding stabilizer to allow it to reach
carburetor.
_) CHANGE OIL:
Change oil if it has not been changed in the last three (3) months.
See "CHANGE OIL" instructions in" MAINTENANCE" section.
_) OIL CYLINDER BORE:
A. Remove spark plug and poor one (1) ounce (30 ml} of clean

GENERAL
Just as your automobile needs professional mechanical mainte-
nance from time to time, so does your Craftsman engine. Replace-
ment of the spark plug and air cleaner is made necessary by
NORMAL use. Professional Air-Cooled Engine Service is as close as
your nearest Sears Roebuck and Co. (or Sears Canada, Inc.) Service
Center.
A yearly check-up or tune-up by Sears is a good idea to avoid
breakdowns or delay.., do it at the end of the season, then you're
ready for the next. We even prepare it for storage for you.
