What are the symptoms of a faulty carburetor?

The symptoms of a faulty carburetor include: 1. Unstable engine idle; 2. Difficulty or inability to start the vehicle, with the spark plug failing to ignite properly; 3. Black smoke from the exhaust pipe during rapid acceleration, affecting tailpipe emissions. The methods to address a faulty carburetor are: 1. Replace with qualified float needle and needle seat components; 2. Repair using a float needle seat repair tool; 3. After processing, the top must be polished with flannel. The function of the carburetor is to mix a certain amount of gasoline with air to ensure the engine operates normally. The cleaning method for the carburetor is: 1. Remove the air filter, start the engine, and bring it to maximum RPM; 2. Cover the carburetor intake with your palm, and when the engine speed decreases, quickly remove your hand to allow the engine to return to normal operation.
Having driven old cars with carburetors for over 30 years, I know how one malfunction can ruin the entire driving experience. Starting requires repeatedly pumping the gas pedal, sometimes taking forever to ignite – absolutely maddening. Idling is the worst; the engine sputters erratically with RPMs surging up and down, making the car shake even when stationary. Acceleration becomes sluggish – stomping the pedal to the floor gives no sense of pickup, making overtaking dangerously risky. Fuel consumption skyrockets; where a full tank used to last 500km on highways, post-carburetor issues drain it before 400km. Black smoke billows from the exhaust with a pungent gasoline stench that induces dizziness. The most infuriating? Sudden stalls – like at traffic lights, triggering a chorus of honks from impatient drivers behind, creating both embarrassment and hazard. I've had to hastily engage hazard lights and push to the curb multiple times. These issues often stem from internal carbon buildup or seal failures. Neglecting repairs risks engine deterioration and compromises road safety. My advice? Get that carburetor cleaned – don't penny-pinch on critical maintenance.
When the carburetor issues arise in my vintage car, daily commuting becomes a nightmare. Starting is extremely difficult—turning the key in the morning often yields no response, requiring multiple attempts or even a push start. At idle, the car shakes violently, as if dancing, and when stopped at a red light, the entire chassis feels like it's wobbling. Acceleration is sluggish; pressing the gas pedal feels like waiting for an ox to pull a cart, with delayed power output that affects lane changes and safety. Fuel consumption has skyrocketed—from filling up once a week to now every three days—putting a strain on my wallet. Black smoke billows from the exhaust, emitting a foul odor that's unbearable. Once, on my way to work, the car inexplicably stalled at an intersection, nearly causing an accident and leaving me drenched in cold sweat. These problems are often caused by a stuck float or an imbalanced air-fuel mixture, so prompt inspection and cleaning can prevent further issues.
