Try changing the carburet0r adj
gustment slightly. Inject OH around
the inlet manifold TO see il il is
drawn in a. any leaks. and test the
spark az each plug by removing j.
and holding DO about "a quarter inch
from head OF plug while engine is
running. Crank engine slowly and
nOfc the resistance on each cylinder
Il see if there is loss or compress

Motor Depar ment-CcUll you tel
re what the difference is between 81
high tension distributor and "a timer!
III. l..
The high tension distributor takes
care Of and distributes the high ten
sion or secondars current TO the
various cylinders at timed intervals.
The timer simply interrupts 1t timed
intervals the primary current. The
primary current is obtained from q
generator or storage battery. and
this is stepped mp TO a high voltage
current by means of The induction
coil The timer and distributor are
necessary i'm order 70 have the spark
delivered 20 the respective cylinders
in the proper firing order al the
proper time.
Motor Department. Please let me
know why 1 have TO spin my engine

f. ON battery by simply pulling up
ON the starting handle Can IT. be
possible that the battery gives q hot
ter spark than the magnetic
thought IT was just the Teverse.
Y. s.
The magnetic gives hotter spark
than the battery when Dc is running
at proper speed. but not when start
Ina. The battery gives the same
spark regardless of engine speed.
When starting the engine on bat

spark should DE advanced. Try mag
neto with spark advanced and give
a sharp quick turn.
