5 CARBURETOR ADJUSTMENT GUIDE

1 T.O.

RICH LEAN

T.O.

T.O. = TURNS OPEN

Normally the correct setting of the mixture screws is the following:

L (close the screw completely and then open): 1 ¼ ÷ 1 ½ T.O.

H (close the screw completely and then open): 1 ÷ 1 ¼ T.O.

Based on various factors as altitude, ambient temperature etc. it might be necessary to reset the carburetor to optimize
the performance of the engine.

ATTENTION:

Never lean too much as lean mixture will overheat engine and cause seizure

Do not force H or L closed. It may damage the precision machined orifice and render the carb unserviceable.

The adjustment of screw must be performed with warm engine.

(H)

Adjust T.O. from closed to
approximately

1 ¼ .T.O.

(L)

Adjust T.O. from closed to approximately

1 ¼ T.O

(I)

Close by further 1 ½ T.O.
after contact with throttle
lever.

Start the engine and warm it. If RPM too
high adjust

counterclockwise until clutch is

disengaged.

Turn c.c.w. until max. R.P.M.
is reached. Adjust further
fractionally for rich idle.
Trigger accelerator.

If R.P.M.
decreases

(L)

Slowly adjust clockwise

If R.P.M.
increases

Continue  to  turn  clockwise
until  max.  R.P.M.  is  reached.
Adjust  c.c.w.  fractionally  for
rich idle.
Trigger accelerator.

Engine is now idling at max. attainable
R.P.M. or slightly lower on rich side.

Adjust

counterclockwise until 2000 ÷ 2500

R.P.M. is reached.

Recheck

screw for optimum setting

required.

Adjust

until best possible free speed is

reached. Turn clockwise for higher R.P.M.
Counterclockwise for lower R.P.M.

Adjust
