Slight correction PD\ be necessary.
Use a WDFKRPHWHU to set the high speed
adjusting screw + to obtain the highest
possible engine speed. From that
position, turn the high speed adjusting
screw + 1/8 counterclockwise (richer)
or as far as stop. Avoid risk of engine
damage which can be caused by lack of
lubrication and overheating -
•
Check air filter and clean it if
necessary.
•
Set idle speed correctly.
•
Warm up the engine.
Turn the high speed adjusting
screw + and low speed adjusting
screw / clockwise (leaner) at
higher altitudes.
Turn the screws very slowly and
carefully - slight changes have a
noticeable effect on the engine’s
running behavior.
