New Carburetor For TORO 6.5HP GTS 22IN Recycler Lawnmower Carb Tecumseh Engine 20370

6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number.

Carb or CARB may refer to:

• Carbohydrate, a simple molecule
• Carburetor, a device that blends air and fuel for an internal combustion engine
• California Air Resources Board, in the government of California, US

A carburetor (also spelled carburettor or carburetter) is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the Venturi effect or Bernoulli's principle or with a Pitot tube in the main metering circuit, though various other components are also used to provide extra fuel or air in specific circumstances.

Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, but carburetors are still used by some small engines (e.g. lawnmowers, generators, and concrete mixers) and motorcycles. In addition, they are still widely used on piston-engine–driven aircraft. Diesel engines have always used fuel injection instead of carburetors, as the compression-based combustion of diesel requires the greater precision and pressure of fuel injection.

An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy.

Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form; thus heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing.

Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine in which heat from the combustion of a fuel causes rapid pressurisation of the gaseous combustion products in the combustion chamber, causing them to expand and drive a piston, which turns a crankshaft. Unlike internal combustion engines, a reaction engine (such as a jet engine) produces thrust by expelling reaction mass, in accordance with Newton's third law of motion.

Apart from heat engines, electric motors convert electrical energy into mechanical motion, pneumatic motors use compressed air, and clockwork motors in wind-up toys use elastic energy. In biological systems, molecular motors, like myosins in muscles, use chemical energy to create forces and ultimately motion (a chemical engine, but not a heat engine).

Chemical heat engines which employ air (ambient atmospheric gas) as a part of the fuel reaction are regarded as airbreathing engines. Chemical heat engines designed to operate outside of Earth's atmosphere (e.g. rockets, deeply submerged submarines) need to carry an additional fuel component called the oxidizer (although there exist super-oxidizers suitable for use in rockets, such as fluorine, a more powerful oxidant than oxygen itself); or the application needs to obtain heat by non-chemical means, such as by means of nuclear reactions.

Tecumseh ( tih-KUM-sə, -⁠see; c. 1768 – October 5, 1813) was a Shawnee chief and warrior who promoted resistance to the expansion of the United States onto Native American lands. A persuasive orator, Tecumseh traveled widely, forming a Native American confederacy and promoting intertribal unity. Even though his efforts to unite Native Americans ended with his death in the War of 1812, he became an iconic folk hero in American, Indigenous, and Canadian popular history.

Tecumseh was born in what is now Ohio at a time when the far-flung Shawnees were reuniting in their Ohio Country homeland. During his childhood, the Shawnees lost territory to the expanding American colonies in a series of border conflicts. Tecumseh's father was killed in battle against American colonists in 1774. Tecumseh was thereafter mentored by his older brother Cheeseekau, a noted war chief who died fighting Americans in 1792. As a young war leader, Tecumseh joined Shawnee Chief Blue Jacket's armed struggle against further American encroachment, which ended in defeat at the Battle of Fallen Timbers in 1794 and with the loss of most of Ohio in the 1795 Treaty of Greenville.

In 1805, Tecumseh's younger brother Tenskwatawa, who came to be known as the Shawnee Prophet, founded a religious movement that called upon Native Americans to reject European influences and return to a more traditional lifestyle. In 1808, Tecumseh and Tenskwatawa established Prophetstown, a village in present-day Indiana, that grew into a large, multi-tribal community. Tecumseh traveled constantly, spreading the Prophet's message and eclipsing his brother in prominence. Tecumseh proclaimed that Native Americans owned their lands in common and urged tribes not to cede more territory unless all agreed. His message alarmed American leaders as well as Native leaders who sought accommodation with the United States. In 1811, when Tecumseh was in the South recruiting allies, Americans under William Henry Harrison defeated Tenskwatawa at the Battle of Tippecanoe and destroyed Prophetstown.

In the War of 1812, Tecumseh joined his cause with the British, recruited warriors, and helped capture Detroit in August 1812. The following year he led an unsuccessful campaign against the United States in Ohio and Indiana. When U.S. naval forces took control of Lake Erie in 1813, Tecumseh reluctantly retreated with the British into Upper Canada, where American troops led by Richard Mentor Johnson engaged them at the Battle of the Thames on October 5, 1813, in which Tecumseh was killed. His death caused his confederacy to collapse. The lands he had fought to defend were eventually ceded to the U.S. government. His legacy as one of the most celebrated Native Americans in history grew in the years after his death, although details of his life have often been obscured by mythology.
