HOW TO DRIVE A MOTORCAR
so positioned. iNo! There is the ubiquitous small
boy to contend with, and there is the man of more
mature age but with equal curiosity, either of whom
may elect to move the change-speed lever.
At night, of course, the equivalent to this is moving
the lever sideways so as to make sure that it is in the
centre of the gate. This principle, if studiously prac-
tised, is a pretty safe guard against the possibility
of damage through starting up the car with a gear in
mesh.
“Feeling” the Handle
Another method, however, resorted to by the
writer is that of “ feeling ” the starting handle. To
those mechanically-minded this expression may be
obvious, but for the sake of others it is as well to
elucidate it.
Instead, then, of grasping the starting handle and
so soon as it is in mesh swinging the engine, “ feel ”
the rotary progress of the starting handle for an inch
or two, so as to see if the engine is quite free from
engagement with the gearbox. An inch of movement
made quite slowly is sufficient to assure one that every-
thing is well for starting up, and then the cranking
motion can be completed quickly as usual.
It is very rare that an engine stops just in front
of dead centre, and, as most motorists are aware, the
firing point is usually some few degrees before the dead
centre. If the engine stops near dead centre at all it
is far more usual for it finally to remain stationary
just after the firing point than in any other position.
It would serve no useful purpose for the moment to
go into theoretical reasons for this, but observant
motorists will probably have noticed the fact for them-
selves, though perhaps not bringing it down to so many
words ; in other words, it is usually found that there is
an appreciable amount of movement before the firing
stroke. Probably the pistons have stopped in mid-
position, or else the engine is about on dead centre,
and in the latter case the last piston, which would have
fired had the switch been on, has just passed the
point at which the spark would have occurred. Con-
