II generator stops generating cur
rent. but the danger ~ not as great
as you suppose. Your ignition sys-
tern docs not draw 20 amperes
when running, but more nearly 5 or
g. When speeded up II draws less
than arnpere. The high reading
vou get with engine at rest rs due
10 the low resistance OF the system
and the fact that the interrupter
points make good contact. When
running the interrupter points touch
for 30 short a time that very little
current Is used.

the cause was a weak spark. The

Motor DepartInent:-Plea help
me to locate a knock IN Any Ford.
About two weeks ago my crank
shaft broke, which also broke Cylin-
Ger block. Put In new parts. in
GLIDING pistons. and had engine
thoroughly OverhRuled. Differential
and universal in good shape. but
knock Is Just as bad as ever. Knock
is loudest when running down hill
or ialing. 4 valve litter pin IS tight
and sometimes sticks Timing gears
and oamshsft appear TO be in per-
feet condition H. 8
Valve guide tight, allowing valve
20 remain up, would be a cause OF
knock. This viii not happen II
spring can push IL down again.
There may be too much space be-
tween valve filters and valve stems.
Probably some adjustment or con-
meeting rods or other parts have
been overlooked and left loose.
Nothing but reinspection OF the
parts can determine this.
Motor Department - Are larger
ay-wheels used with 12 cylinder en-
gines or with four cylinder en-
Eines7 L c.
The more cylinders we have the
less the hy-wheel IS needed. go that
hy-wheels on eight and 12-cylinder
engines are smaller than those on
four and six cylinder engines On
