Carburetor for Stihl FS46 FS55 FS75 FS80 FS85 HT70 HT75 FC55 FC75 FC85 Trimmer Replaces ZAMA Style

Product Information

With the engine running, give full throttle, then turn the “H” knob to the right until the reduction in speed begins. cc engine will come to life, with the inbuilt electronic ignition module ensuring easier starting and continuous firing of the motor. In the photo below you can see what a clean filter looks like and dirty (the parts are separated by a dash). This defect of the adjusting lever causes problems with the inlet, as well as improper engine idling. The throttle valve determines the amount of air for supply, and engine power directly depends on this.

Simply put, adjusting the carburetor on the lawn mower is creating the optimal fuel mixture due to the correct air supply. Broken parts of the shaft can enter the combustion chamber or crankcase and cause serious damage to the entire piston system. The cavity, which is located below the membrane, is connected to the atmospheric air through the hole (19). It’s easy to operate with one hand, with the simple trigger switch on the handle, your hand will never have to leave the strimmer’s controls.Also, the aforementioned consequences for the engine may cause clogging of the pump cavity with impulse side. The lightweight frame and engine of grass trimmer will reduce the stress on your lower back whilst operating. Also exist screwless carburetors, responsible for the enrichment of the combustible mixture at low speeds. The piston located in the cylinder, making a reciprocating motion, successively changes the pressure in the crankcase (vacuum or pressure increase). The position of the throttle (9) determines the amount of air entering the carburetor chamber, as well as engine power and the number of revolutions.

change to a new one or clean the air filter (it is recommended to wash it in warm, soapy water, squeeze it out and let it dry well). Since the volume under the control membrane (18) is connected with atmospheric air through the channel (19), the membrane goes up, opening the valve (14) by means of the lever (17). By turning it to the left, the engine speed will begin to decrease, and when you turn the regulator to the right, the speed will increase. The smaller this hole, the faster the air flows, and the higher the level of its rarefaction in the zone with the smallest diameter. At this time, fuel from the chamber (16) is sucked through the jets (11,12), after which it is mixed with the flowing air.

As a result, the contact surface takes the wrong position, which disrupts the additional fuel supply. But, since the design of this module, as well as its operating principle, is largely similar between different models, a generalized description of the processes occurring in the carburetor can be made. To eliminate problems with air purification, it is necessary to replace the defective filter or rinse the existing one (serviceable).
