CARBURETOR
PILOT SCREW REMOVAL (For E-28, 33)
Because harsh cleaning solvents can damage the O-ring seals
in the pilot system, the pilot system components should be
removed before cleaning.
• Use a 1/8" size drill bit with a drill-stop to remove the pilot
screw plug. Set the drill-stop 4 mm (0.16 in) from the end of
the bit to prevent drilling into the pilot screw. Carefully drill
through the plug.
• Thread a self-tapping sheet metal screw into the plug. Pull on
the screw head with pliers to remove the plug. Carefully clean
any metal shavings from the area.
• Slowly turn the pilot screw clockwise and count the number of
turns until the screw is lightly seated. Make a note of how
many turns were made so the screw can be reset correctly
after cleaning.
• Remove the pilot screw along with the spring, washer and O-
ring.

• After cleaning, install the pilot screw 1 to the original setting
