An the engine Is fitted with alumni
mum It can easily be accounted for BY
the greater clearance when the engine 10
cold. This clearance Is taken up as
the engine gets warm. Even iron piS-

as the aluminium. 1t ma be possible

II. n. y.
A-rhe hard starting may Be caused
by a weak magnetic, poor plugs, wide
gaps, or a poor mixture. II mlsfires At
such high speed, probably because the
carburetor doesn't feed right II wasn't
to feed for any length Of Tina

shouldn't Try to do more than that II

You recently told one of your readers
that you knew Of no method Of intensi-
flying your lights at ten miles per hour
with a Ford Standard equipment. r
have obtained results after Q great deal
OF experimenting. and this may be Of
help to some OF your other readers.
1st-A type C lamp will give a much
brighter light at all speeds than the
regular Ford lamp will give at the same
.peed.
2d-A method Of cutting out one lamp.
thereby using all available current in
he lamp IN use. will double its light at
ow speeds. but there l. a possibility
u burning out il driven at high speed.
3d-Connecting each lamp direct with
instead OF In series, as in regup
ar Ford equipment, will double the
mount OF light. but you may not have
sufficient current to operate horn with
lOiu l6ulS on. Also GlGTe the ia
,llity OF burning out lamps at high
peeds, as in starting engine with light
witch on, and in driving about twenty
I've miles per hour.
The third method is what ! am now
lsing. and have a switch which 1 have
made and mounted on the steering COL
mn by means OF which I can cut out
ne lamp. leaving the other burning.
To connect lamps in this way. diScon-
ect the wire that passes from the right
and lamp to the left hand lamp, and
n place Of it connect a short piece Of
iire from right hand lamp to some con-
enient part OF car frame Ito around
he lamp, and for left hand lamp run
n extra wire from lamp to light switch.
Id timers assembly wires may be used
Or this purpose. or single wire. such
s is used for drop cord in house wiring :
suitable.
Use 9v lamps and carry a spare lamp
r two Of 2Y. in case the 9v lamp should
urn out. The Nv lamp will not give
5 good a light, but may save you sit
ng in the dark IL the others should
urn out In my right hand lamp. ri
Sc 9v. but the left one always burns
ut the 9v. so use 12v in II. I
find that the average driver OF a &
ord does not think he can dim his
Shts in passing another machine, and
he way most Ford lights are set. they
re very binding to the other driver.
In passing another car. throw gears in
eutral and slow down the engine, and
lie other fellow will have a chance.
ook after the lamps, and II they IL
inmate the tree tops, as most OF them
