How to replace the accelerator torsion spring of 20 14 Steele chainsaw?

Loosen the adjusting screw of the tension spring, remove the old tension spring, hang a new tension spring and tighten the adjusting screw. The simple carburetor consists of three parts: the upper part has an air inlet and a float chamber, the middle part has a throat, a metering hole and a nozzle, and the lower part has a throttle valve. The float chamber is a rectangular container, which is used to store gasoline from the gasoline pump. There is a float in the container, and the oil intake is controlled by the oil level on the floating surface.

Cleaning method of throttle valve

Look for the throttle position, which is behind the air inlet and connected to the air cleaner. Remove the plastic hose connecting the throttle and air cleaner first, then remove the air cleaner assembly, then remove the throttle cable, unscrew the anchor bolt, then remove the throttle, apply special cleaning agent or carburetor cleaning agent, and spray it on the throttle, waiting for the organic solvent to dissolve the carbon deposit.

During the whole cleaning process, disassembly, painting and installation are inconvenient, but the cleaning effect is very good. However, we should pay special attention to the fact that the throttle surface has a layer of anti-fouling and anti-static architectural coating. If the cleaning is too frequent or the cleaning solution is unreasonable, the coating will be lost, and the throttle will be dirty in the future.
