What if the carburetor can't supply oil?

Solution to the problem that the carburetor can't supply oil: If the carburetor can't supply oil, add some pencil lead or talcum powder to the throttle knob of the plunger carburetor, and then inject sewing machine oil into the throttle line and vacuum carburetor with a medical syringe, and check whether the tightness of the throttle return spring and vacuum membrane is broken or not properly installed and closed. The carburetor does not return oil. You can add some pencil lead or talcum powder to the throttle knob of plunger carburetor, and then inject sewing machine oil into the throttle line with a medical syringe. Vacuum carburetor, check whether the tightness of throttle return spring and vacuum membrane is damaged or not properly installed and closed.

Carburetor failure:

1 First of all, it is necessary to determine whether the throttle valve of the carburetor cannot be reset, or whether the engine speed is not reset or reset slowly after the throttle valve is closed;

2. If the throttle of the carburetor does not return, the fault is still caused by the throttle pipe and throttle hand. If the throttle pipe and throttle handle are normal, check whether the carburetor is improperly installed, which will cause the throttle to be too tight in the carburetor. After tightening the mounting screws, some inferior carburetors will not be able to lower the throttle. Check whether the throttle valve does not return due to the influence of engine heat on carburetor, and install heat insulation pad if necessary. Check whether there is a problem with the installation angle of carburetor, which causes the throttle pipe to be stuck after installation;

3. If the engine speed does not return or returns slowly (the throttle valve returns when it falls forward, and the throttle valve is a cylindrical part with an oil needle pulled by the throttle line), check whether the carburetor is improperly debugged, or the mixing ratio, etc. , and check whether the carburetor has slight air leakage, etc. Sometimes a slight air leak in the carburetor or valve will also cause the vehicle speed to slow down. Check whether the replaced carburetor is of an inappropriate model or has quality problems.
