axles do not turn at low idle.

statts_ you may need to adjust the
carburetor and idle screws
(contimled)

yon'It see the two carburetor,
adjustment screws next to the choke
button. (Picture 1)
The "RED" screw is the HIGH-
speed adjustment..rtae "WHITE"

First, remove the tines fl_om the
axle. Then start engine, Let it run for
two to fl_ree minutes, "FLASH" the
choke several times during the warm-
up to clear any air from the Fuel
system
Then stop the engine after it
reaches operating temperature.
Now, turn the RED, high-speed
screw counter-clockwise all the way to
stop . Then turn the WHITE, low
speed screw halfway between the
counter-docl_vise and clockwise stop
positions
Now restart the engine to finish the
carburetor adjustment
Run the engine at full speed two or
three seconds Io clear out any excess
fuel Then return to idle
No_; accelerate [he engine to full
throttle several times to check for a
smooth transition from idle to high
speed
If the engine hesitates turn the
WHITE, low-speed screw counter-
dockwise one-eighth of a turn, Then
accelerate the engine.
Repeat the adjustment until you get
a smooth transition to high speed

How to Reseat
the Flange

your Filler for several },ears.. Or
perhaps you've removed the
engine for use with our hedge
trimmer attachment, then
replaced it, In either case, the
flange bolt (Key #38, page !8)
may have come loose and lifted
the engine up,
If this happened you'll
notice a gap between the
bottom of the engine clutch
case (Key #37_, page 18) and

worm gear housing Notice the
hex head on top of the drive
shaft (Key .-"-9,Page 16). Inside
the clutch case, you'll find the

lines up with the clutch drum
inside the clutch case
