on th e crankcase cover (see fig. 14) . With the flywheel in
this position check whether the contact breaker points are
correctly set at 0,4 mm . ( .0157") . Pl ace now a piece of tissue
paper between the points and turn the flywheel anticlockwise
till the paper is firmly gripped. Turn again the flywheel clock-
