Recoil Starter
Pull out the starter rope (Figure 25) and inspect it for
fraying. If its condition is questionable, replace the rope as
described in Chapter Nine.
Check the action of the starter. It should be smooth, and
when the rope is released, it should return all the way. If
the starter action is rough or if the rope does not return,
service the starter as described in Chapter Nine.

and operation of the engine. Check the exhaust system
from the cylinder exhaust port to the muffler for damaged
gaskets, loose or missing fasteners or damaged compo-
nents. Refer to Chapter Five.

clean the corrosion and reattach. Make sure the wires are
correctly routed and do not rub against moving parts or
touch hot (especially exhaust) parts,
