A non-road engine is provided. The non-road engine includes a carburetor and a combination switch for controlling on-off of a fuel supply pipe between a fuel tank and the carburetor, where the carburetor is provided with a control valve for controlling opening and closing of a main jet; the control valve is linked and matched with the combination switch; when the combination switch is in an on state, the control valve causes the main jet to be in an open state; and when the combination switch is in an off state, the control valve causes the main jet to be in a closed state.

An engine balancing system includes an engine body. At least two slider-crank mechanisms are provided inside the engine body. One of the slider-crank mechanisms is arranged opposite to the other slider-crank mechanism. A slider in one of the slider-crank mechanisms is moved at a speed and acceleration similar to a speed and acceleration of a slider in the other slider-crank mechanism. The slider-crank mechanism includes a connecting rod and a crankshaft with a crank. One end of one of the slider-crank mechanisms and one end of the other slider-crank mechanism are connected to the same crankshaft through the crank. The balancing system can effectively eliminate first-order, second-order and higher-order vibrations generated during engine operation, thus reducing the probability of equipment damage.

An automatic control apparatus for a carburetor choke valve includes a pull-rod, throttle control lever, choke block, and temperature control assembly which is arranged on a cylinder head through a bracket having a rotating shaft and coil spring. The rotating shaft is connected to the spring and one end of the pull-rod via a rotary arm. The other end of the pull-rod is located at a choke valve shaft. The block and valve shaft are connected to respective ends of the lever. During cold start, the block is opened driving the lever to pull the valve shaft. When rotated through a certain angle the valve shaft is blocked by part of the pull-rod, such that the valve and block cannot be fully opened. During warm start, the valve shaft when returning is blocked by another part of the pull-rod such that the valve cannot fully close.
