it refuses to start on battery. How

and is it anything serious? T. r.
The trouble is in the battery circuit
breaker. Remove cover and inspect
carefully TO see if any parts are loose.
Draw a piece of fine emery cloth
through the breaker points several
times to clean them. See IL breaker
moves freely. If not, spring is loose,
broken, or a drop of oil is needed on
pin on which breaker turns. Also test
size of gap by means of gauge on the
wrench supplied by the manufacturers.
If no gauge is handy a piece of metal
one sixty fourth of an inch may be
used.

with a mere touch, but Is subject to
electrical difficulties. The mechanical
horn requires pressure to be applied
and may develop mechanical difficult
ties. so it would seem to be a matter
for each one to decide for himself.
