STARTING DECOMPRESSOR
Though the engine is provided with an automatic decompressor,
can be necessary, in some cases (carburetor flooding or starting
difficulties due to a battery inadequate charge), to use the man-
ual starting decompressor on the L.H. side of the handlebar. In
these cases, pull the lever (5) whilst simultaneously pressing
the starter button, release the lever (5) keeping the button
pressed and afterwards release the latter as well.
In order to adjust the lever decompressor free play (approximately
3 mm- 0.12 in.), the lever holder is provided with the adjuster (6);
the adjustment can be also effected with the tightener (7) on the
R.H. side of the engine (use this tightener if it is not possible to ob-
tain the correct free play with the adjuster on the handlebar).
