Precursors:
1. If it is light (small gap), the car will be weak and unable to refuel uphill.
2. Even more serious, there is no idle speed, or the engine shakes strongly at idle, and the exhaust makes an explosion noise when refueling! And sometimes there will be a refueling fire accompanied by explosions.
3. If the gap is too big, it won't start at all. When some models start the engine, you will hear a crashing sound in the engine, which is the sound of the top of the piston hitting the engine. valve. Many problems can arise when the timing is out of whack. They are all caused by damage inside the machine head. If it is serious, it can be revised.
4. The timing mess won't happen by chance. As long as the timing belt is replaced once a year, the tensioner is checked during installation,the tension force is adjusted and the timing mark is installed as needed. Everything will be alright.
Detailed information:
Cars with manual transmissions are particularly prone to stalling. At this point you mustz go to the repair shop to check the car's start accelerator, fuel injector and other problems. If it can be ruled out, make sure you do so. check if the timing belt is defective. If there is a problem, replace it in time if it is aged or cracked.

If it is a piston carburetor, it is a typical phenomenon of needle falling of main oil. However, the generators are all general purpose gasoline engines with rotary valve butterflies. Gasoline must also be pumped behind the throttle (throttle opening is increased), but gasoline cannot be increased simultaneously.
As an experiment, cover the air inlet and the accelerator pedal with your hand. You should feel your hand being sucked in and, at the same time, gasoline should be sprayed into your palm. If the throttle valve canbe increased in this way, the problem still lies in the oil level being too low or the foam hole in the main nozzle not being clear.
