Frequent stalling of the Honda Phantom 150 may be caused by issues in the fuel supply system, a clogged carburetor, a damaged self-priming pump, or excessively low fuel tank level. Specific reasons: Engine air leaks, incorrect spark plug electrode gap, or blocked idle jets in the carburetor can all lead to sudden stalling while riding. Solutions: Adjust the throttle adjustment screw and air adjustment screw. If idle still cannot be maintained, remove and open the carburetor, use a wire with a diameter smaller than 0.4mm to clear the idle jets and idle air passages, then use an air pump to blow out all passages. Alternatively, check if the fuel level in the carburetor float chamber is too low, or if there are air leaks in the reed valve or crankcase.
