Secure the cowl with 6 M2.5x8 wood screws. Route fuel lines from
the cowl. One is the fuel filler line and the other goes to the muffler
pressure fitting. The final line is from the engine breather fitting
(4-cycle) and vents via a piece of aluminum tubing held in place on the
muffler with small tie wraps (Photo 92).
