Passat Yu Ling 06 is equipped with a throttle after washing. Is there oil and fire but no car?

If there is no fire, please check 1 and check the valve clearance. If it is wrong, it needs to be adjusted. If your car is DHOC, you will be annoyed. The valve gasket is not easy to find. 2. Check the spark plug to see whether the model is correct and whether the electrode gap is between 0.7 and 0.9. Observing the combustion situation at the same time is helpful to judge the adjustment of carburetor. It is strongly recommended to choose high-quality imported spark plugs with correct calorific value, and beware of counterfeiting. 3. Measure the compression ratio. If there is no cylinder gauge, cover the spark plug hole with a piece of tissue paper. If the paper is sucked violently when starting, it is ok. Pay attention. You can make your own air nozzle and install it on the spark plug hole, and use the pump to check the air leakage. 4. Oil inspection. It is best to remove the oil tank and use the container to force the oil delivery, because there is a possibility that the switch of the negative pressure oil tank will fail. In addition, see if the interface glue between carburetor and engine leaks.
