The reasons why a scooter frequently stalls when decelerating are as follows: 1. Clogged fuel filter screen: Insufficient fuel supply after accelerating causes the engine to stall. After stopping, gasoline flows back into the float chamber, allowing the scooter to restart. However, when accelerating again, the fuel level in the carburetor drops, and the main jet cannot draw fuel, leading to another stall. 2. Clogged carburetor main jet: This may be due to dirty gasoline or long-term inactivity of the scooter, causing fuel deterioration and forming deposits that block the main jet. 3. Engine overheating causing slight cylinder expansion: If the cylinder is expanded, it is necessary to go to a repair shop to replace the cylinder block, piston, and piston rings.

What is the penalty for stopping on a pedestrian crossing and what type of violation is it?

Stopping on a pedestrian crossing is considered over-line stopping and is subject to a fine and a deduction of 2 points. Article 90 of the "Road Traffic Safety Law of the People's Republic of China" states: "Motor vehicle drivers who violate road traffic safety laws and regulations regarding road traffic rules shall be given a warning or fined. If this Law provides otherwise, penalties shall be imposed in accordance with the relevant provisions." Below are the penalty standards for other parking violations: 1. If a motor vehicle is parked in violation of regulations, the traffic management department of the public security authority may issue an illegal parking notice or record the violation using electronic monitoring equipment. If the parking obstructs the passage of other vehicles or pedestrians, the motor vehicle may be towed to a location that does not obstruct traffic or to a designated parking area, and the driver shall be fined. 2. If a motor vehicle is temporarily parked in violation of regulations, a fine shall be imposed. 3. If a motor vehicle is parked or temporarily stopped in a location with no-parking signs or markings, a fine shall be imposed, and 3 points shall be deducted.

What to Do If the Air Filter Gets Wet

Water in the air conditioning filter can affect the engine and may lead to engine water ingress. Here are the relevant solutions: 1. Replace the Air Filter: First, turn off the engine to prevent water from entering the engine and causing hydraulic lock. Open the air filter housing, clean out the water (check if there is water in the cylinders), and have a simple cleaning done at a reputable repair shop. Then, replace the wet air filter. 2. Install the Air Filter: When installing, pay attention to the orientation of the filter to avoid installing it backward. After installation, check if the filter is properly seated. The filtering surface should cover the entire air duct, and the edges should fit tightly. Otherwise, it may result in filtration failure.

Does the Timing Chain of the Old Tiguan Need to Be Replaced?

The chain also needs to be replaced, but not on a regular basis. It should be replaced based on actual conditions—when there is a malfunction or abnormal noise. If there are no issues, replacement is unnecessary. The chain won't break, but it may stretch. When stretched or if the tensioner malfunctions, the chain may skip teeth, which can damage the engine by impacting the valves. Functions of the timing chain: 1. Drive the engine's valve train: It ensures the intake and exhaust valves open or close at the right time, allowing the engine cylinders to intake and exhaust normally. 2. Drive: Chain-driven systems are reliable, durable, and space-saving. The entire system consists of gears, chains, and tensioning devices. The hydraulic tensioner automatically adjusts the tension, maintaining consistent chain tension and requiring no maintenance throughout its lifespan, making it as durable as the engine itself. 3. Robust and durable: Timing chains have inherent durability, offering peace of mind without concerns about "long-term neglect" or "breaking down at critical moments." However, when the vehicle's total mileage reaches 100,000 kilometers, the drawbacks of the timing chain begin to emerge.

Is it a problem if the car key is dropped?

You can try using the remote control; if it works, then it's not broken. The chip inside the key is relatively fragile, so be careful not to drop it frequently. Dropping it occasionally is fine. Below are solutions for what to do if you lose your car key: 1. Use the spare key: Generally, cars come with two keys, one for regular use and the other as a spare. If the regular key is lost, the spare key can be used. Therefore, it's important to remember not to keep the spare key in the car; always store it in a safe place at home. Otherwise, if the regular key is lost and the spare key is also in the car, you'll have to call a locksmith. 2. Professional locksmith services: If the car is far from the spare key or the spare key is also lost, you should contact a professional locksmith company to unlock the car. Usually, you'll need to provide proof that the car belongs to you, such as an ID card or vehicle registration. 3. Visit a 4S shop: Every car comes with an anti-theft code. By providing the vehicle registration and personal information to the 4S shop, they can retrieve the anti-theft code and configure a new key. Additionally, they can erase the data of the lost key, rendering it invalid for starting the car (though it may still open the door). Therefore, the 4S shop may also recommend replacing all the locks for added security.
