1. Remove the individual plastic bags from the box and place
them on a table or workbench. Remove the engine from its
plastic wrapper. Note: Some engines may already have the
carburetor installed, but make sure that the carb retaining bolt
is tightened.
2. Inspect the carburetor retainer to insure that the curved portion
of the carburetor retainer drawbar matches the inside wall of the
air intake port. If it does not, simply place it in position with
your finger. Next, remove the tools from their protective
wrapper. You will need the Allen wrench to tighten the
carburetor retainer. (As noted above, some engines come
with the carburetor already mounted.)
VERY IMPORTANT:
An improperly installed O-ring
may lead to unreliable performance.
3. Remove the O-ring from the parts bag. Install the O-ring into
the cavity of the air intake port of the crankcase, as shown in
Photo 2 , making sure that the O-ring is seated evenly at the
bottom of the cavity and cannot come in contact with the
engine crankshaft. The second O-ring is a spare. Insert the
carburetor into the intake port.
