via the chain to the engine. See that the sprockets have their arrows facing as previously
mentioned. Move the ignition control lever to the limit of its motion of advance. Remove
the cover of contact breaker and slowly turn the armature till the fibre block of the make and
brake lever arises on the inclined plane of the steel segment just sufficient to separate the
points. This is the firing point, and with the piston in the position referred to above the sleeve
and sprocket should register if correctly fitted up. If so, the drive should he fixed up as
before detailed. It is, however, always advisable to check the timing idler tightening up,
Magneto Adjustment.—Examine the driving chain occasionally, and, if slack, it
must be tightened. The magneto is carried behind the cylinder, on a platform which is
pivoted at its rear end, and can be raised in order to take up any chain slack. To adjust
the chain, the front and rear bolts should be unscrewed a turn or two and the platform raised
from the forward end. When the desired chain tension is arrived at carefully retighten the
bolts.
REAR WHEEL ADJUSTMENT GAUGE
On the right-hand side of the bottom chain stay will be found a piece of sheet metal,
held in position by a clip which passes round the tube.
In the tool kit will be found a flat gauge that can be fitted round the rim (see
Illustration).
When replacing the rear wheel after removal, or after making adjustment
to chain, place the gauge on the rim with the extension to the right, and set the wheel so
that the edge of the gauge just touches the plate that is held by the clip on the chain stay.
REAR WHEEL ADJUSTMENT GAUGE.
This ensures the wheel being correctly aligned and must be done before finally tightening
up the spindle nuts. Do not attempt to unscrew the clip from the chain stay, as the position
of the plate is set correctly before the machine leaves the factory.
It is important that this gauge should bed properly on to the rim on both sides;
the best method of ensuring this being to see that the hooked end is properly encircling the
bead of the rim. Then pull the gauge end into place firmly.
