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.
