What to Do if Your

En_ne Idles too High

What if your engine runs too fast or if the tines turn the instant you

start the Iiller? You may need to adjust the idle screw (Key #19 under Carburetor on page 17) by itself right

it counter-clockwise lbu'll know

you've adjusted it correctly when the axles do not turn at low idle.

What to Do it Your

Engine Runs "Rough"

If },our engine runs "rough" or statts_ you may need to adjust the carburetor and idle screws

Picture t

If you remove the air-cleaner cover, 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" screw is the tow speed adjustment

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

At some point, you may find that the tines won't turn when

you press the throttle This may mean the enDne isn't sitting all the way down on the worm gear housing

Pertaaps you've been using

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

Picture 2 Note how the engine sits all the way down on the transmission

the top of the worm gear housing (Picture 1)

_b fix this, loosen the flange bolt Take the engine off fl_e 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 clutch drum (Key #31, Page

29). Make sure the hex head

lines up with the clutch drum inside the clutch case

Then put the engine back on the worm geat housing Make sure the plastic carrying handle is not under the fue! tank,

If you've followed these steps

properb; there _411 be no gap between the clutch case and the

worm gear housing (Picture 2) Make sure you tighten the flange bolt!
