Turning now to an efficient burner for heating the ignition tube, Frank
started with an ordinary wick-type kerosene lamp with a small metal
tank. Wishing to use gasoline in the lamp, he found it necessary to
fabricate a number of burner units before he found a type that gave him
a clean blue flame. He then found the flame to be very sensitive to
drafts and easily extinguished, and devised a small shield or chimney to
afford it some protection.

Early in October, while still working with the burner, Frank developed a
severe headache. He felt the fumes of the lamp had probably caused it,
and went to his room in the home of a Mr. and Mrs. Patrick on Front
Street in Chicopee. After he noticed no improvement, a doctor's
examination showed he had typhoid fever, and on October 5 he was
admitted to the Springfield Hospital. Here he remained for one month,
being discharged on November 5. Returning to his room he was informed
that because of the fear that he might be a typhoid carrier, the
Patricks preferred him to find other lodgings. He readily accepted the
invitation of Mr. and Mrs. D. H. Nesbitt of Chicopee to take a room with
them. After several weeks recuperation in their home, he left
Springfield to visit his mother in Wyoming, Illinois.

After a restful visit at home Frank Duryea returned to Springfield and
finished the work on his burner. Now only the lack of a carburetor
prevented a trial of the vehicle. He recalls that he studied several
gasoline-engine catalogs and in one of them, a Fairbanks catalog he
believes,[16] he saw a design that seemed to suit his needs. He decided
to simplify the construction and operation of his carburetor and had a
small bronze casting made to form the body of it. Inside was a gasoline
chamber with two tapped openings, one to receive a pipe from the
2-gallon gasoline tank mounted above the engine, the other taking a pipe
to the overflow tank underneath the engine, thus maintaining the
gasoline level without the use of a float valve. This latter tank had a
hand pump on one end so that the overflow gasoline could at times be
pumped again into the main tank. Gasoline passed from the carburetor
chamber through a needle valve, adjusted by a knob on top, then through
a tiny tube that entered the pipe leading to the intake valve. It is not
certain whether this intake pipe was at first fitted with the choke
arrangement later used with the second engine.
