(1) First check the oil level in the float chamber. In plain areas or hot areas, it is better to control the oil level to 1~1.5mm below the engraved mark. If the oil level is too high, it can be adjusted. If the oil level is adjusted to the specified standard and the oil level does not change after starting, and it works normally, the fault has been eliminated.
If the oil level cannot be adjusted to the standard position, disassemble the carburetor and check whether there is oil in the float. If there is oil, the float is broken and should be repaired or replaced. If the float is not broken and the installation position and shape have not changed, check whether the triangular needle valve is not closed tightly or is stuck, and repair or replace it. After the float or triangular needle valve is repaired or replaced, reinstall and adjust the oil level, and test the engine. If the working condition is restored, the fault has been eliminated.
(2) If the oil level in the float chamber is normal, you can remove the air filter and check whether the choke is fully open in the vertical position. If the choke is stuck or cannot be in the fully open position, it should be repaired. Test again
(3) The opening position of the choke door is normal, there is no jamming phenomenon, and the test is normal without installing the air filter. You can check whether the air filter element is clogged due to excessive dirt and should be cleaned or replaced with a new one.
(4) If the above steps are normal, the carburetor should be removed and disassembled for further inspection. First check whether the vacuum and mechanical fuel-saving ball valves are closed tightly. If they are not closed tightly, you must consider the problem of the main measuring hole and adjust or replace it. (1) First, check the oil level in the float chamber.
