DASH

SYSTEM

These

carburetors
are

equipped

with
a
dash

pot
interlocked
with
the

primary
thrott
Ie
valve

through
a

link

mechanism

The
dash

pot
prevents
the

throttle

valve

from

closing
abruptly
thereby

reducing
He
emissions

during

tion
or

gear

In

transmissi9fi
models

it

also

prevents

from

In

the

and
the
condition
of

oil
around
the

gauge
should
be

examined

every
S

Ion

miles
This
is

an

easy
and
effective

trouble

shooting
procedure
since
some

changes
in

oil
condition
are
often

linked
with

developed
troubles
For
instance

Lack
of
oil
causes
defective

opera

tion

by

making
the
clutches
and

brakes

slip
resulting
in

severe
wear

This
is

because
the
oil

pump
sucks

air

causing
oil

foaming
thus

rapidly

deteriorating
the
oil

quality
and

pro

ducing
sludge
and
varnish

Excessive
oil
is
also
bad
because
of

oil

foaming
caused

by
the

gears
stirring

up
the
oil

During

high
speed
driving

excessive
oil
in

the
transmission

often

hlows

The
