I have a new 1914 - car when, mas
not been run more than 100 miles. There
has suddenly developed a whlstllng,
grinding noise in the motor when am
at loss to locate want TO make all
my own repairs if posSible:-DWner-
You probably are familiar enough
with The mechanism of the car to prop
erly lubricate all the working parts
Such q noise may arise from a dry ran
bearing or a coupling which IS IN need
of fabrication It may also be poSSlDle
that the water pump is the cause OF the
trouble Oftentimes in the centrifugal
tyne pump the propeller Will WOIA
SLIGHTLY out of position on the shaft and
scrape against the housing OF the pump
This can be remedied by removing
pump and either moving the propeiler
slightly on the shaft or else trimming
the blades slightly. Possibly by EASING
up on the packing nuts at each end or
the pump housing the noise Will De

VIII YOU please explain why the arr
cooled engine is used so successfully
on motorcycles and IS not seIie dlI -
adopted by automobile makers. 1t
seems to me that the aIr-cooled en-
CINE is much simpler, and that if 1t is
practical in one case II should De IN
the Other.-W- l. S
II is fact that d small cylinder can
be kent cool better than a large GYM
der In a large cylinder the wall area
is less than that in small cylinder IN
proportion to the volume OF the COM
bustion chamber. The drop in the tenn
perature of the small cylinder IS much
more rapfd than that of the larger cyl
inder Likewise in cooling methOdS
Far i a
draught the larger cylinder has less
advantage in that one side Is cooled ana
the other is not. This is bound to cause
more or less Warpage and undue Irlc-
ton Then again, in the motorcycle
the small engine is usually exposed
whereas in the automobile engine II Is
covered with a hood and background
cutting off the cooling:
