3. Insert a long thin rod or tool into the hole on the
cross shaft and rotate the shaft clockwise
(viewed from the end) as far as it will turn, then

Connect the governor spring (with long looped
end), to the inner hole on the governor lever and
control bracket.
Connect the governed idle spring to the outer
governor lever hole and control bracket. The long
end of each spring must be toward the governor
lever. Make sure the springs do not contact the
valley baffle. See Figure 10-103.
