Chainsaw hot start difficulties, mainly because of heat dissipation problems, especially in the summer high temperatures, the following we say how to solve the starting difficulties.

Chainsaw hot machines are difficult to start and usually involve the whole machine's heat dissipation. This is when the machine heat dissipation is not good, the heat can not be discharged from the machine and conductive accumulation to the carburetor, so that the carburetor temperature is too high, up to or even beyond 40 degrees, gasoline through the carburetor into the cylinder before the volatilization of gasoline and can not be a normal supply of fuel caused by. This situation is especially likely to occur in the summer and the chainsaw to do work within 20 minutes of flameout.

In this case, we usually need to let the machine cool naturally or manually accelerate its heat dissipation, just the carburetor temperature down can be used again. Here to popularize a little knowledge, to make the carburetor accelerate the heat dissipation, we can use a few drops of gasoline in the carburetor above so that the heat will also be evaporated, and the carburetor will be able to work normally.

In short, a hot engine hard to start, scientifically speaking, is due to the machine casing and other unscientific designs to make the machine heat dissipation of bad lead, especially when the surrounding climate temperature is already high, especially easy to happen!

In addition, high temperature can also easy to cause the carburetor needle valve to stick, this is off-topic, in this case, the problem caused by the carburetor can not be started, as long as you open the carburetor back cover, dial the black diaphragm (dosing diaphragm) below the needle valve and then re-installed can be!
