Swift's solution to overload throttle

The throttle is heavy because the throttle is dirty, which has nothing to do with adjustment. The solution is simple. Disassemble the joint between the air filter and the intake branch pipe, spray some carburetor cleaner in the throttle (hold the throttle pipe with your hand as the throttle, and then the valve in the throttle valve body will open, so that more areas can be cleaned), and wipe it with a clean cloth, which will remove some black dust.

Throttle, also known as "throttle" and "throttle". Refers to the control device that controls the engine power (thrust). On the piston aero-engine, the throttle valve controls the opening of the carburetor to control the filling amount of the cylinder, thus determining the output power of the engine. On the gas turbine engine, the throttle valve controls the metered fuel flow of the fuel regulator, thus determining the thrust generated by the engine. The position of the throttle is controlled by the driver operating the throttle lever in the cockpit, and it is transmitted to the carburetor or fuel regulator on the engine through control system components such as pull rod, rocker arm, torsion tube, steel cable, pulley and sector wheel. On an airplane, the throttle lever is always pushed forward to increase power (thrust) and pulled back to decrease power (thrust).
