在使用小型汽油机时,应做好对化油器的保养,注意“清洁、密封、零件完整、转动灵活”等几个技术环节。特别是化油器的密封问题,必须予以重视。在实际使用中,化油器与缸体接触平面不平或垫片及绝热片破裂,乍看起来是“小事”,其结果却会因“漏气”而引起进入气缸的混合气过稀,导致“放炮”和怠速不稳,甚至难以启动。可见化油器的密封对于汽油机工作的重要性。因此,在使用保养化油器中必 In the use of small gasoline engine, should be done on the carburetor maintenance, pay attention to “clean, sealed, complete parts, flexible rotation, and several other technical aspects. In particular, the sealing problem of carburetor must be given attention. In actual use, carburetor uneven contact with the cylinder block or rupture of gaskets and insulation films, at first glance appears to be ”trivial“, the result will be due to ”leak“ caused by the mixture into the cylinder too thin, resulting in ”Blast" and idle speed instability, or even difficult to start. Seen the carburetor seal the importance of gasoline engine work. Therefore, the use of maintenance carburetor must
