mended R.P.M., loosen main adjustment screw until
engine starts to cut out. Then turn screw opposite
direction until engine starts to cut out. Note the num
ber of turns from one extreme to the other. Loosen
screw to a point midway between the extremes.
After the main system is adjusted, move the speed
control lever to the idle position and follow the same
procedure for adjusting the idle system.
Test the engine by running it under a normal load.
The engine should respond to load pick-up immedi
ately. An engine that “dies” is too lean.
An engine which ran rough before picking up the load,
is adjusted too rich.
If adjustment seems too “touchy” check float for prop
er setting and for sticking.
8 H.P. ENGINE
Preset the carburetor by turning both idle and main
adjustment screw closed (clockwise) fingertight. Open
the main adjustment screw 2 turns (counterclockwise)
and the idle adjustment screw 1 -3/4 turns.
Generally, the engine will perform well with these set
tings. If further adjustment is required, perform the fol
lowing adjustments with the engine running and fully
warmed up.
With speed control lever at idle or slow speed, turn
the idle adjustment screw slowly, clockwise 1/8 turn at
a time until the lean drop off point is reached. (The
engine will miss and run erratically due to lack of fuel.)
Now turn the screw counterclociwise 1/4 to 3/8 turn
from that position. This will be the best setting.
