What To Do If Your Engine
Runs “Rough”
If your engine runs “rough” or stalls, you
may need to adjust the carburetor and idle
screws.
If you remove the air-cleaner cover, you’ll see
the two carburetor adjustment screws, next
to the black choke button.
The “RED” screw is the HIGH-speed adjust-
ment...The “WHITE” screw is the low speed
adjustment.
Start the engine and let it run for two to
three 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 operat-
ing temperature.
Now, turn the RED, high-speed screw count-
er-clockwise all the way to the stop...Then,
turn the WHITE, low-speed screw halfway
between the counter-clockwise and clockwise
stop positions.
Now restart the engine to finish the carbure-
tor adjustment.
Run the engine at full speed two or three
seconds to clear out any excess fuel. Then
return to idle.
Now, accelerate the 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-clockwise one-eighth of
a turn. Then, accelerate the engine.
Repeat the adjustment until you get a
smooth transition to high speed.
Cleaning the Muffler Screen
1. Take out the spark plug.
2. Remove the red cylinder cover (Key #19)
which is held on by two Phillips-head screws.
(Key #18).
3. You will see the metal screen fixture, held
on by 3 more Phillips-head screws (Key #26).
Remove the fixture.
4. Behind the fixture (Key #25) will be the
muffler lid (Key #24) and muffler lid gasket
(Key #23). The screen sits in the gasket.
5. If the screen (Key #22) is clogged with
deposits, it needs to be cleaned. Use carbure-
tor cleaner, and any brush that is not metal.
Brush the screen until you are able to see
through it.
6. If the screen remains plugged after
attempts at cleaning, it must be replaced.
