Motor Department-Wiu you
kindly inform me as 20 how much
horse power ls consumed By 2 gen
orator on a car rated at IS horse
power? OWNER
The mount Of power consumed
hv the generator IS not worth con-
Steering. IL would not use mucn
more than a magnetic or wa-er
pump. and so would not make
enough difference in the running Of
The engine 20 De noticeable.
Motor Department-When my
engine is running, and especially
when laboring. it develops a knock.
There - also a hissirg sound, evil
IDENTIFY a leak. Such a leak prob
ably would cause loss Of power. Am
correct2 Where should 1 look
for these troubles? T. D
The knock may be due 20 piston
elan (caused by worn pistons) or
70 accommodations Of carbon. II
some part Of the engine Is loose the
engine will have to be taken down.
Look for the kissing noise by In
iectinz oil around the spark plugs
relief valves and valve caps Any /
leakage viii cause loss Of power.
Motor Observation-Disclosures at-
wise me on the following: I have |
an Overland which I am overhaul :
ing and find tha- the grooves IN
the No. / and No 3 pistons are
twentv-thousandths of an inch /
wider than the rings in the other I
two. Would this cause a knock or /
poor compression l.. n 4
This condition OF grooves would !
.ermit a loss OF compression. The /
rlav Of the rings i'm grooves would
also cause Sigh. knocking each +
time the piston starts on stroke. /
Would suggest that YOU have /
grooves trued 10 fit new oversize
rings
Motor Department. have a /
Dodge car run only 100 miles. and /
am having trouble with tappets. u
had them frightened about six weeks
ago and now they are loose again.
Can they be frightened so as not TO /
work loose in so short ,ime2 W.
When the tappets are adjusted I
and properly locked they should re-
main so indefinitely. A careful In
spectlOn should determine whether
they are defective or not. If they
do not hold heir adjustment per
hans YOU will find that the threads
ere stripped This is caused by
using too powerful wrenches.
Motor Department. find my en-
CINE is badly carbonized, but live
far away from any supply Of oXy-
gen for burning It out. is there any
other way % remove carbon, by
scraplng or otherwise?
READER
Carbon may be scraped out, US
irg the three tools called CARBON
scrapers. but IL is apt 10 stay on the
piston and go out with the exhaus-
and clog the muffler. II the de-
post Is not very heavy It may be
reduced by pouring half a teacup-
etl OF kerosene into each cylinder,
through the compression cocks
while the engine Is hot Close
cocks and crank engine over COM
presslon 70 force vapOr into carbon.
Leave over night Some OF the
carbon viii burn out when next
the engine Is run.

We suppose you mean the ground
brush on the magnetic It conducts
