MAINTENANCE AND REPAIR
ASSEMBLY ·TORQUES
Assembly torques as given here require the use of a torque wrench.
,These assembly torques. will assure proper tightness without danger of
stripping the threads. If a torque wrench is not available, you will have
to estimate the degree of tightness necessary for the stud, nut or screw
being installed and tighten accordingly. Be carefut not to strip the
threads. Check all studs, nuts and screws often. Tighten as needed to
prevent them from working loose.

CARBURETOR. -
CarbUretor maintenance should consist of regular
cleaning. Some types of gasoline have a tendency to-

the float is not damaged. If necessary to reset the f1oan~vel,
a small screw drlv-er to bend the lip of the float, With the,carbure-
toi: casting inverted and the float resting llghtly against the needle in its
. seat, clearance between the bowl cover gasket and the free end of the
float should be 5/16"(7/32" ifa "DAY" reservoir tank is used) •

Carburetor adjustments appear inthe ADJUSTMENT section herein. Be
slire the throttle assembly works freely. When reinstalling adjusting
needles, do not force them into their seats.
