1945 training film shows how to overhaul the carb of a Piper Cub aircraft. Produced by Audio Productions.
Originally a public domain film from the US Office of Education, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

The Piper J-3 Cub is an American light aircraft that was built between 1937 and 1947 by Piper Aircraft. The aircraft has a simple, lightweight design which gives it good low-speed handling properties and short-field performance. The Cub is one of the best known light aircraft of all time. The Cub's simplicity, affordability and popularity — as well as its large production numbers, with nearly 20,000 built in the United States — invokes comparisons to the Ford Model T automobile.
The Cub was originally intended as a trainer and had great popularity in this role and as a general aviation aircraft. Due to its performance, it was well suited a variety of military uses such as reconnaissance, liaison and ground control. It was produced in large numbers during World War II as the L-4 Grasshopper. Large numbers of Cubs are still flying today. Notably, Cubs are highly prized as bush aircraft.
The Cub is a high-wing, strut-braced monoplane with a large-area rectangular wing. It is powered by an air-cooled piston engine driving a fixed-pitch propeller. Its fuselage is a welded steel frame covered in fabric, seating two people in tandem.
The aircraft's standard chrome yellow paint has come to be known as "Cub Yellow" or "Lock Haven Yellow"...
The Taylor E-2 Cub first appeared in 1930, built by Taylor Aircraft in Bradford, Pennsylvania. Sponsored by William T. Piper, a Bradford industrialist and investor, the affordable E-2 was meant to encourage greater interest in aviation. Later in 1930, the company went bankrupt, with Piper buying the assets, but keeping founder C. Gilbert Taylor on as president. In 1936, an earlier Cub was altered by employee Walter Jamouneau to become the J-2 while Taylor was on sick leave. (The coincidence led some to believe that the "J" stood for Jamouneau, while aviation historian Peter Bowers concluded that the letter simply followed the E, F, G and H models, with the I omitted because it could be mistaken for the numeral one.). When he saw the redesign, Taylor was so incensed that he fired Jamouneau. Piper, however, had encouraged Jamouneau's changes and hired him back. Piper then bought Taylor's share in the company, paying him $250 per month for three years.
Although sales were initially slow, about 1,200 J-2s were produced before a fire in the Piper factory, a former silk mill in Bradford, Pennsylvania, ended its production in 1938. After Piper moved his company from Bradford to Lock Haven, PA; the J-3, which featured further changes by Jamouneau, replaced the J-2... Powered by a 40 hp (30 kW) engine, in 1938, it sold for just over $1,000.
A number of different air-cooled engines, most of flat-four configuration, were used to power J-3 Cubs, resulting in differing model designations for each type: the J3C models used the Continental A series, the J3F used the Franklin 4AC, and the J3L used the Lycoming O-145. A very few examples, designated J3P, were equipped with Lenape Papoose 3-cylinder radial engines.
The outbreak of hostilities in Europe in 1939, along with the growing realization that the United States might soon be drawn into World War II, resulted in the formation of the Civilian Pilot Training Program (CPTP). The Piper J-3 Cub became the primary trainer aircraft of the CPTP and played an integral role in its success, achieving legendary status. About 75% of all new pilots in the CPTP (from a total of 435,165 graduates) were trained in Cubs. By war's end, 80% of all United States military pilots had received their initial flight training in Piper Cubs.
The need for new pilots created an insatiable appetite for the Cub. In 1940, the year before the United States' entry into the war, 3,016 Cubs had been built; wartime demands soon increased that production rate to one Cub being built every 20 minutes...
