Whether there is oil in the engine, whether the carburetor oil pipeline is normal, whether there is no dirt in the engine heat sink, whether there is no obstruction! Whether the engine temperature is higher, generally about after the crash is 95℃ above, whether the engine has lubricating oil, the engine has no overload!


Reasonable analysis

(for example) assume only the temperature is high, other normal, can directly exclude the oil supply lubrication circuit cooling system!


When the intake of jose did not reach the next stroke down, the intake valve closed, in this process, the engine operating load increased, the line of compression, combustion for the vacuum state, although the post explosive force is insufficient, exhaust, such as exhaust insufficient, the engine will appear serious high temperature high heat!

When the lubricating oil flow heat dissipation takes away all the heat, resulting in overheating of the entire engine, when the temperature reaches 85 degrees above, the piston running in the X-axis direction, began to leak, in addition to the excessive operating load, the engine will gradually like no oil out!


Based on the problems encountered in the above examples, according to the theory, the valve interval is too large and the valve lift is short. We only need to adjust the valve interval.

Open the valve cover and adjust the valve screw to the expansion clearance of a piece of iron. After valve debugging, it is recommended to debug the mixing ratio. The mixing ratio adjustment is recommended to find professional personnel to adjust, and it is more troublesome for individuals to adjust.
