1. Theoretical analysis of reasons for failure to start

理論上來說， 如果按照正確的起動方法反復起動三次， 而小型汽油發(fā)電機仍不能成功起動?？赡艿脑蛴幸韵聨讉€方面：

Theoretically, if the correct starting method is repeated for three times, the small gasoline generator still can not be started successfully. The possible reasons are as follows:

1 ）小型汽油發(fā)電機油箱無油或油路堵塞； 油路部分堵塞， 使得混合氣太稀。或因多次起動造成進入氣缸的混合氣太濃。

1) There is no oil in the oil tank of small gasoline generator or the oil circuit is blocked; The oil circuit is partially blocked, making the mixture too thin. Or the mixture entering the cylinder is too rich due to multiple starts.

2 ） 點火線圈有問題如短路、 開路、 受潮或接觸不良； 點火時間不當或位角不對。

2) The ignition coil has problems, such as short circuit, open circuit, damp or poor contact; Improper ignition time or wrong position angle.

3 ） 火花塞間隙不當或漏電。

3) Improper spark plug clearance or leakage.

4 ） 磁電機的磁鐵性變弱； 斷電器白金太臟、 燒蝕、間隙過大或過小。電容器開路或短路； 高壓線漏電或脫落。

4) The magnetism of magneto becomes weak; The platinum of the breaker is too dirty, ablated, and the gap is too large or too small. Capacitor open circuit or short circuit; Leakage or falling off of high voltage line.

5 ） 氣缸壓縮不良或氣環(huán)漏氣。

5) Poor cylinder compression or gas ring leakage.

小型汽油機燃油供給系零件少，結構相對簡單。油機長期停用后， 機油的沉淀易造成堵塞化油器油道量孔。 所以應該先檢查油路。 按下啟動加濃按鈕， 檢查化油器供油暢通情況， 發(fā)現有燃油從化油器進氣口流出， 說明化油器供油暢通； 可以不拆卸化油器， 這

The fuel supply system of small gasoline engine has few parts and relatively simple structure. After the oil engine is stopped for a long time, the oil precipitation is easy to block the measuring hole of carburetor oil passage. So you should check the oil circuit first. Press the start enrichment button to check the smooth oil supply of the carburetor. It is found that fuel flows out of the air inlet of the carburetor, indicating that the oil supply of the carburetor is smooth; It's OK not to disassemble the carburetor

也進一步說明不需要再檢查集濾器是不是堵塞。 通常情況下， 對汽油機而言， 集濾器的油道容易被膠狀物堵塞， 如有堵塞， 可取適量的汽油浸泡清洗后， 再用細竹簽 （例如牙簽 ） 疏通即可。

It is further explained that it is not necessary to check whether the filter collector is blocked. Usually, for gasoline engines, the oil passage of the filter collector is easy to be blocked by colloids. If it is blocked, soak an appropriate amount of gasoline for cleaning, and then dredge it with a fine bamboo stick (such as toothpick).
