es of the engine to pass through the heat
jacket of the carbureter when engine is idling and to regulate the
volume of this heat as throttle is opened by automatically opening the
Main-Exhaust-Heat-Valve, thus allowing the increasing volume of the
exhaust gases to pass on out through the main exhaust pipe without being
deflected and by-passed to the carbureter heat-jacket as the motor speed
increases.

[Illustration: HEAT SETTING No. 1]

By referring to the cut shown (See Page 5) and noting "Heat Setting No.
1," it will be noted that valve "C" in main exhaust line is fully closed
with the closed or idling position of the throttle valve. This
adjustment is accomplished by having long connecting rod "R" from valve
"C" Lever set in "Hole No. 1," in Throttle Lever "L," being sure that
when throttle valve is standing in fully closed or idling position that
valve "C" is also in closed position, proving out the latter feature by
loosening connection of valve "C" lever holding long connecting rod;
holding Throttle Lever "L" in closed or idling position and bringing up
valve "C" lever on connecting rod "R" as far as it will go to the right
toward the carbureter and tightening its connection on the connecting
rod in that position. After having made the adjustment as just
described, it is assured that "Heat Setting No. 1" has been properly
made and that all of the heat possible from the exhaust has been
secured.

This "Heat Setting No. 1," provides as stated, for the most exhaust heat
obtainable and should be used during the entire year, except in
extremely hot seasons or hot climates or when high-test gasoline is
being used in engine and even then unless engine is losing power due to
excessive heat.

If loss of power or mileage due to too much heat is experienced, first
be sure that it is not due to driving on hot-air instead of cold-air.
After making this observation, if there is still too much heat, refer to
cut (See Page 7) describing "Heat Setting No. 2." It will be noted that
connecting rod "R" from valve "C" is removed from "Hole No. 1," in
Throttle Lever "L" and placed in "Hole No. 2," in Throttle Lever. This
change is all that is necessary in order to reduce the amount of heat
applied to carbureter. In "Heat Setting No. 2," when the throttle is in
closed or idling position, valve "C" is quite aways off its seat. This
adjustment provides for a great deal less heat than is provided by "Heat
Setting No. 1" and is all th
