2. Slide the cowl back into place. Align the front of
the cowl with the crankshaft of the engine. The
front of the cowl should be positioned so the
crankshaft is in the middle of the precut
opening. Hold the cowl firmly in place using
several pieces of masking tape.

it in place using four 3mm x 12mm wood
screws.
