ADJUSTMENTS
CARBURETOR ADJUSTMENT
Test the engine by operating the chipper-shredder.
If engine tends to stall or die out, it dsually
indicates that the mixture is slightly lean and it may
be necessary to open ,f',) the needle valve slightly
to provide a richer mixture This richer
mixture may cause a slight unevenness in idling.
If any adjustments are made to the engine
while the engine if running {eg. car-
buretor), keep clear of all moving parts
Be careful of heated surfaces and muffler
Minor carburetor adjustment may be required to com-
pensate for differences in fuel, temperature, altitude or
toad
NOTE
A DIRTY AIR CLEANER WILL CAUSE
ENGINE TO RUN ROUGH BE CERTAIN
AIR CLEANER IS CLEAN AND ATTACH-
ED TO THE CARBURETOR BEFORE
ADJUSTING CARBURETOR DO NOT
MAKE UNNECESSARY ADJUSTMENTS
FACTORY SETTINGS ARE SATISFAC-
TORY FOR MOST APPLICATIONS AND
CONDITIONS.
Never attempt to change maximum engine speed It is
pre-set at the factory and should be changed only by
a qualified service technician who has the necessary
equipment,
The carburetor may need re-adjusting if engine lacks
power or does not idle properly if adjustments are
needed, proceed as follows.
To Adjust Carburetor:
1. Close needle valve (See figure 16) clockwise
(("_ } finger tight only Forcing may cause damage_
Then open 1-!/2 turns counterclockwise (r'x)
2. Start engine and allow to warm for five minutes.
3
With throttle in RUN position, close needle valve
clockwise (;-_,) until engine starts to lose speed
(lean mixture). Then slowly open needle valve
counterclockwise (f'_) until engine JUST BEGINS
to run unevenly This mixture should be rich enough
for best performance under load.
Place throttle control in IDLE position:
a_ If engine idtes, no further adjustment is
necessary.
b tf engine idles too fast, turn idle speed
adiusting screw counterclockwise _(-",) until
slower speed is obtained
c If engine dies, turn idle speed adjusting screw
