Slowly turn the idle adjusting needle

flOODING

(Excessive

fuel mixture

in combustion chamber)

This condition can be created by over

choking, tipping the engine to an extreme

forward angle or cranking a hot engine

with the use of the

choke

which

may

cause toO much fuel to be drawn into

the

crankcase and combustion chamber. The

fuel mixture therefore becomes too rich

for combustion. Also it may be possible

that the shut-off needle in the

carburetor

does not seat properly and allows the fuel

to flow unrestricted into the

crankcase.

tion under fuel tank, continue to crank

the engine until it starts and re-open shut

off cock fuel valve under fuel tank. If the

carburetor continues to overflow with

fuel after the

engine has started, gently

tap the body of the

carburetor which

and

cleaning may be necessary to

correct

this

condition

if not remedied by above

method

Extreme cases of flooding occur

when the engine has been allowed to

stand with the spark plug in a downward

position causing a large quantity of .fuel

to run into the crankcase and combustion

chamber. If this occurs, remove the

spark

plug and drain the fuel from the combus

tion chamber, because you will not be

able to turn the engine over by hand

with

a large amount of fuel in the combustion

chamber. Wipe spark plug terminals dry

with a

rag.

(Be

sure to tighten spark plug

sufficiently to eliminate the danger of a

compression leakage around the

plug.)

GOVERNOR (Pneum atic

air velocity type)

When

the governor is operating prop

erly, the air vane

will

be activated by an

air stream created from the finned fly

wheel in the blower housing. The forces

of the air against the air vane are counter

balanced by the tension created by a cali

brated

governor spring.

Loss of engine

speed will

decrease

the air velocity

against

the air vane and allow the air vane to be

moved

counter-clockwise

by the calibrated

governor

spring tension which will open

the throttle on the carburetor to imme

diately restore the engine speed to the

constant governor setting

The opposite

is true when the engine increases speed.

The air blast is immediately increased

against

the air vane and forces the air

vane clockwise which in turn closes the

throttle

the carburetor to reduce the

engine speed thus created, and maintain a

constant setting of the

speed

on the en

gine at all times. To insure proper opera

tion, the governor spring must be free to

move. The linkage connecting the air

vane and carburetor must be free from

dirt deposits so as not to disturb the bal
