s.Wlii YOU please tell mo whether Q
cylinder should leak compression past
che rings when stopped on dead cen
teri If3it should not leak, how do you
remedy this?
The rings should be tight enough 50
that no appreciable loss of pressure
WIN occur for, say. minute. but II
cannot be expected that the pressure
WIN stay there indefinitely when the
piston Is stopped on dead center. From
fl,e why your question is worded 1t
seems that you have turned the motor
over until one Of the pistons has
reached the end OF the compression
stroke and that you left It there Tor q
6aw moments at least. II, however,
we have misunderstood you and the
fact actually Is that when you turn
the motor over slowly without stop
ping the pressure decreases then you
have a leak. 1t may not be the 1ault-
az the rings, however. but due to the
valves. If the trouble is due to leak
ing rings they must be replaced. and II
the Distons and cylinders are very
badly worn it mayl i. necessary to bore
ont the cylinders and fit larger rings
Before going to the trouble of tearing
down the motor and examining the
pistons and rings remove the exhaust
yalye and note whether it Is carbon
tied or pitted. IL so it must be ground.
Also note whether there is any clear
anca between the valve stem and the
push rod. There should be sufficient
space to insert a piece OF writing pa
per, and if there is not the push roo
must be adjusted by loosening the lock
ntit..whfchs is. the lower one. and then
turning the upper nut to the right -
there is NO clearance the valve VIII be.
held off its seat and leakage will occur.
II tie exhaust yalye-is found to be. In
rood condition examine the inlet valve.

The knock Is due to some loose part,
which must be found by process OF
elimination. Probably you will find
chs knock by examining the main
bearings for looseness, the fywheel
connection and the crank shaft, which

Il Ia REMOVING carbon from gasoline enc

Apply the alcohol when the motor Is
hot for the reason that the action OF
the alcohol IS merely tor dissolve the

Of carbon together into hard. SOLID

every part OF the carbon. 1t Is best to
do one cylinder at a time. Bring the
piston to top dead center on the COM

closed. FIJI the cylinder with alcohol

depends ON how hard the carbon Is.
