Emergency measures for motorcycle cold car not to start

Check the combustion of the spark plug and reduce the gap slightly. Clean and adjust the carburetor to ensure that the choke valve can work normally. If necessary, the mixer can be slightly thickened, or the oil needle of the throttle valve can be raised by one grid. Check the valve clearance. If the valve clearance is too small, it will affect the cold start. Keep the parallel power sufficient, and the high speed at startup can improve the startup effect. Before starting, you can set the throttle handle without opening the key door. First, step on the starting lever several times with your foot (if you have a foot to start), and be careful not to twist the throttle. Then turn on the ignition switch and start the engine. After starting, don't rush to send the throttle back. Wait until the engine runs stably and then gradually send it back to the throttle.
