As long as you are soIEs TO remove
the cylinders II IS best first 80 soak
them in kerosene. rs you suggest ms

/ What !. the difference IN eenStrae-
I ton 5et~eer ordinary and cord ttresE
! Ordinary tires use fabric carcass or
I one usade OF g tough grade Of duck or
I canvas. u lille cord tires are built up on
a cord carcass tie latter usually being
4 woven IN such a way as TO tnpart
! great diagonal strength, rendering the
/ tire less susceptible TO vertical stress
than with some other Constructions
VIII you please explain the difference
between the dual, deueIe, single, es"o
! point and duplex electric ignition sys-
TENS?
The dual system employs two tnde-
pendent sources OF current. but uses 2
common ser OF spark plugs and COM
mon high tension distributor The doo-
| bic system employs two independent
| systems throughout. with two sets OF
/ Shark plugs. two sources Of fsuit!on-
two coils aud two distributors The
| single ignition system has but one
| source OF current. one transforming
system, one distributor and one set OF
| plugs. Two point ignition Is where
two sparks occur at the same time IN
| the cylinder. 1t must OF necessity.
| therefore. involve two sets OF Plugs and
! syncIlronized distributes
Duplex ignition Is that n which both
/ a battery and magnetic current source
are used. but IN which the battery Is
connected with the magnetic armature
! in such a way that &c can produce
| high tension spark by Ieeans o. the
secondary winding OF tie magnetic or
aid the primary az low motor speeds.
