Symptoms of a broken scooter carburetor include: 1. If the carburetor is damaged, the spark plug on the ignition system will also burn out. When starting the vehicle, black smoke will appear. At this time, checking the ignition system can reveal whether the carburetor is damaged. 2. You can also determine if the carburetor is damaged by using carburetor cleaner. First, remove the air filter, then spray the carburetor cleaner into the carburetor. Next, start the vehicle and observe whether it starts. If it starts successfully, it indicates a carburetor malfunction, which has led to insufficient fuel supply. 3. A damaged carburetor can cause more severe fuel consumption, unstable throttle response, and incomplete combustion. In severe cases, the vehicle may fail to start or experience weak performance. Additionally, due to the inability to filter impurities in the gasoline, it can lead to severe carbon buildup on the valve gasket and spark plug.

There are quite a few common symptoms when a scooter's carburetor goes bad. I've encountered it many times - like when starting, it just won't fire up no matter how long you press the starter button. Or when idling, the engine sputters and shakes unstably like it's sick, easily stalling. Acceleration becomes weak too, with delayed throttle response that makes climbing hills difficult. There's also black exhaust smoke with a pungent smell, indicating incomplete fuel combustion. If left untreated, it could damage the engine. I suggest taking it to a repair shop immediately before minor issues become major problems. During regular maintenance, check the carburetor cleanliness to prevent carbon buildup blockages.

My scooter had a carburetor issue before, and the symptoms were quite obvious. Starting it in the morning was a nightmare—I was almost late several times and even had to push it to get going. Once on the road, the idle speed was unstable; when stopping at red lights, the engine would fluctuate wildly and sometimes even stall suddenly. Acceleration felt like stepping on cotton—no response at all—and fuel consumption skyrocketed, costing me extra money every month. I cleaned it several times with little effect, and only after replacing the part was the problem solved. Everyone, pay attention: don’t ignore these small signs—they indicate components are failing. Regularly check the air filter to avoid a dirty carburetor and keep your scooter running smoothly.

A faulty carburetor on a scooter manifests as starting failure, rough idling, and insufficient power. This may be caused by clogged fuel lines or uneven air-fuel mixture, leading to abnormal engine operation. Don't ignore black exhaust smoke or abnormally high fuel consumption; timely repairs can prevent further damage. Regular maintenance can extend its service life.

Can a 48V Mild Hybrid System Get a Green License Plate?

48V mild hybrid systems cannot get a green license plate. Only pure electric vehicles and plug-in hybrid electric vehicles are eligible for green license plates. Green license plates are designated for new energy vehicles, specifically pure electric vehicles and plug-in hybrid electric vehicles. Conventional hybrid vehicles and gasoline-powered vehicles must use blue license plates. The main difference between plug-in hybrid electric vehicles and conventional hybrid vehicles is that plug-in hybrids require charging, while conventional hybrids do not. Plug-in hybrid vehicles have larger batteries and more powerful electric motors, enabling longer driving ranges in pure electric mode.

Are the side mirrors and rearview mirror the same thing?

Side mirrors and rearview mirror are the same thing. There are three rearview mirrors in a car, two outside and one inside. Every car has a central rearview mirror inside, which allows the driver to observe the situation behind. The more important rearview mirrors are fixed on the doors of the driver and front passenger seats, and these two mirrors are frequently used by the driver. Rearview mirrors are tools that allow the driver to directly obtain external information about the rear, sides, and lower parts of the car while seated in the driver's seat. For the convenience of the driver's operation, to prevent traffic safety accidents, and to ensure personal safety, all countries require that cars must be equipped with rearview mirrors, and all rearview mirrors must be adjustable in direction.
