Causes of difficulty in starting the hot engine of the chainsaw cutting machine

Posted by sere on December 4th, 2020

The heat engine of the chainsaw cutting machine is difficult to start, which usually involves the heat dissipation of the whole machine. This is because when the heat dissipation of the machine is not good, the heat cannot be discharged from the machine and is conducted and accumulated to the carburetor, so that the temperature of the carburetor is too high, reaching or exceeding 40 degrees, and the gasoline will volatilize before entering the cylinder through the carburetor. Caused by inability to supply oil normally. This situation is especially likely to occur in summer and within 20 minutes of the chainsaw cutting machine's work.

When encountering this kind of problem, we usually need to let the machine dissipate heat naturally or artificially accelerate its heat dissipation, and only need to lower the temperature of the carburetor to reuse it. Here is a little bit of knowledge. In order to accelerate the heat dissipation of the carburetor, we can use a few drops of gasoline on the carburetor, so that the heat will also evaporate and the carburetor can work normally.

In short, it is difficult to start a heat engine. Scientifically speaking, it is caused by the poor heat dissipation of the machine due to the unscientific design of the machine casing, especially when the surrounding climate temperature is inherently high, it is especially easy to happen!

In addition, high temperature can easily cause the carburetor needle valve to stick. This is a digression. If this problem causes the carburetor to fail to start, just open the back cover of the carburetor and dial the needle under the black diaphragm (quantitative diaphragm). Reinstall the valve!
