1. Unplu
the wirin
connector at the starter.
Remove the three screws that secure the upper
fuel tank/shroud assembly, and move it off to one
side. While it is not necessary to disconnect the
fuel line, the fuel tank should be nearly empty while
workin
on the startin
system.
2. Remove the two nuts and two bolts that secure the
inner shroud/recoil housin
