The little handsome guy is not good at fire, and it is difficult to fight as soon as the fire is tur

Black smoke from the exhaust pipe indicates that there is too much carbon in the cylinder and insufficient combustion, and the discharge of the gun indicates that the ignition of the spark plug is not normal.

Since the carburetor type was replaced.

Personally, I feel like it's a bit of a stretch. Check it out at the car dealership.

The little handsome guy is also known as the unwarned.

The recommendations are as follows:

1.If the air-oil mixture in the cylinder cannot reach the standard pressure when it is compressed, it is difficult to ignite the oil-gas mixture in the cylinder when the spark plug is ignited, and it will naturally not be able to start. You can check the spark plug to see if it is old, and moreover, clean up the carburetor, adjust the mixing ratio screw, and some starter levers do not return to their own position, which is estimated to be the design and assembly of the machinery itself.

Better cars basically don't have this problem, and some low-end brands are prone to this kind of problem as long as they are used for a little longer. (Key check carburetor and spark plug).

2.The more the motorcycle can not be placed without riding, because the battery is easy to run out of power, easy to break, and the motorcycle should be ridden a little farther, if you just play, not riding for a long time, you will turn off the engine and not ride, and it is not good for the car. If the battery is fine, it is still not good to start, you can go to the place where the motorcycle is repaired and adjust the speed of the car a little higher.

1. Confirm that the clutch plate does not slip, confirm that the battery power is sufficient, confirm that the motor, start the relay, and the clutch are working normally, otherwise replace the clutch plate or even the clutch assembly; Replenish the battery with water, charge, replace the corresponding parts, and confirm that the wiring is normal!

2. Replace 10W 30 (5W 30 in severe cold areas) SF level or above antifreeze ** engine oil, add more than 93 regular station gasoline, turn the carburetor mixture adjusting screw clockwise for half a turn, start the cold car to use the damper, and confirm that the electric damper car is open and closed normally!

3. Check the spark plug, replace the one with low calorific value in a timely manner, check the strength of the high-pressure fire, detect the flashover distance less than 1cm, replace the high-voltage bag, igniter, low-voltage coil (the stator assembly is above the four poles), etc.!

4. Check the pressure in the cylinder, when the pressure is lower than the manual, check, repair or replace the cylinder head gasket, valve, valve seat, piston ring, etc.!

5. Check whether the secondary combustion system of the National II III car, especially the hose connected to the carburetor hose, is aging and cracked, resulting in air leakage!

6. Confirm that the timing chain is not aged, no noise, and the ignition time is correct!

7. Confirm that the electric lock has not aged and entered the water!

8. Confirm that the flame-out line is not short-circuited!

9. Confirm that the start method is correct, and it is powerful!

10. Confirm that the fluid level of the carburetor is normal, the main measuring hole is unobstructed, and the adjustment is appropriate! Through the above comprehensive overhaul, the correct way: start within three kicks, and ignite successfully within two electric starts! It's not easy to answer the question, and mutual aid is upgraded (this talent is two levels!) Sweat! Thank you for adopting!

1. It is recommended that you change a spark plug, if it still doesn't work, check whether your high-voltage spark is normal, the specific method: remove the high-pressure spark cap, let the cylinder line be 1 cm away from the spark plug, not too far, start it, see if it is a blue spark, if the spark is red, it means that there is a problem with the high pressure, you need to change the high-pressure package.

2. Open the damper to try, if you open the damper to ignite, it is your carburetor's business.

Reasons why the motorcycle is not good ignition:

1. Confirm that the clutch plate does not slip, confirm that the battery power is sufficient, confirm that the motor, start the relay, and the clutch are working normally, otherwise replace the clutch plate or even the clutch assembly; Replenish the battery with water, charge, replace the corresponding parts, and confirm that the wiring is normal!

2. Replace 10W 30 (5W 30 in severe cold areas) SF level or above antifreeze ** engine oil, add more than 93 regular station gasoline, turn the carburetor mixture adjusting screw clockwise for half a turn, start the cold car to use the damper, and confirm that the electric damper car is open and closed normally!

3. Check the spark plug, replace the one with low calorific value in a timely manner, check the strength of the high-pressure fire, detect the flashover distance less than 1cm, replace the high-pressure bag, igniter, and low-voltage coil.

4. Check the pressure in the cylinder, when the pressure is lower than the manual, check, repair or replace the cylinder head gasket, valve, valve seat, piston ring, etc.!

5. Check whether the secondary combustion system of the National II III car, especially the hose connected to the carburetor hose, is aging and cracked, resulting in air leakage!

6. Confirm that the timing chain is not aged, no noise, and the ignition time is correct!

7. Confirm that the electric lock has not aged and entered the water!

8. Confirm that the flame-out line is not short-circuited!

9. Confirm that the startup method is correct.

10. Confirm that the fluid level of the carburetor is normal, the main measuring hole is unobstructed, and the adjustment is appropriate!

First of all, confirm that the replacement parts are good, some new parts are not necessarily good, remove the spark plug and inject a few drops of oil into the cylinder, press the spark plug hole with your hand and repeatedly empty it several times, install the spark plug and energize it, add a small throttle and do not move, start, if the throttle is started, do not move, run for a while, try.

Check the electricity (e.g. spark plug fire) first, then the oil (e.g. carburetor), if both are fine, then there may be a problem with your ignition timing (need to be sent to mechanical repair).

Hello! (1) You confirm that the clutch plate does not slip, confirm that the battery power is sufficient, confirm that the motor, start the relay, and the clutch are working normally, otherwise replace the clutch plate or even the clutch assembly; Replenish the battery with water, charge, replace the corresponding parts, and confirm that the wiring is normal! (2) You check the spark plug, replace the one with low calorific value in time, and check the high-pressure fire intensity.

3) When starting the ignition, close the choke to thicken the mixture, and it will start smoothly, but ensure that there is enough power.

Dizzy, I have a three-way oil valve under the fuel tank, one hole is exhausted, you have oil in the exhaust hole, just replace the three-way oil valve.

First of all, could it be that the power is out of power, and secondly, is it possible that the engine is a little cold, and you try to push it for a while and then ignite it.

It is recommended that you try to change the lighter My motorcycle used to have this problem, just change the lighter.

The suction pipe of the self-priming switch of the fuel tank has a leak or is loose.

Cleaning the carburetor is the best option.

1. The idle speed should be adjusted high, 2. Whether the oil pipe and carburetor are normal; 3. Whether the oil has not been replaced for too long, 4. The car should be warmed up at low temperature.

The thing about the engine is high at idle.

The oil is too thick, you should change the oil, there is a lot of carbon deposits in it, and there are a lot of metal chips caused by friction, when the car is hot, the oil becomes thinner, and it is easy to start. It has nothing to do with the mixture.

It should be the flooded cylinder upstairs, remember to loosen the accelerator when driving the rear foot must be careful not to put it indiscriminately, be sure to put it in the position of the brake and wait, the right foot is not in the place of the brake or in the place where there is a door during the whole driving process, must not be placed elsewhere, even if you do not step on the brake when you do not step on the accelerator, you must put it on the brake pedal and wait, put it in another place when you suddenly step on the brake, and pay attention to it in the future.

Tighten the handbrake first, hang up first gear, step on the clutch and brake, start the engine, slowly lift the clutch and brake, see that the front of the car is raised, the rear of the car is a little sinking, and then let go of the brake pedal, slowly let go of the handbrake, refuel and go.

suffocating fire; It's time for the big throttle again; It's easy to drown the tank; It's just that there is too much gasoline in the cylinder, and the computer will still let the fuel injector spray fuel into the cylinder when the ignition is ignited; Shoot like this a few times; It would be good if the concentration of the mixture in the cylinder was normal; There's no need to worry; Be careful when driving in the future, safety first!

The cylinder choked on oil, it's okay, there are any problems, a few black smoke after the resumption of starting, the excess oil will burn out, the car is still the car, the engine is still the engine There will be no problems, rest assured.

If the carburetor does not enter the oil, clean the carburetor and check the spark plug, and replace the battery when it is time to replace it.

It may be that the centrifugal force combiner is broken.

This situation involves many possibilities, first of all, you should check whether the oil and oil lubrication in the engine are normal, whether there is poor lubrication or overheating to stick to the cylinder fault. If the oil and oil lubrication are normal, check whether there are problems with the fuel tank cap, negative pressure fuel tank switch, gasoline filter, etc. Check whether the carburetor mixing ratio is too thick, whether the air filter is blocked, whether the negative pressure fuel tank switch seeps gasoline from the suction pipe into the cylinder, whether the carburetor electronic control damper cannot be automatically closed after heating the car, and is always in a thickened state, etc., they will cause the mixture to be too thick and the hot car will stall.

Check whether the high-voltage ladle, igniter, magneto stator coil, etc. of the ignition system have hot car fire failure faults.

The high-voltage package where the wiring is loose.

Try turning up the idle speed. There is also a possibility that the fuel tank is flooded.

It should be that the amount of oil is not enough, hehe, or the oil supply road is not smooth.

A little handsome guy pedal 125 motorcycle, cold car start at most two or three times can be ignited, but after the ignition, the throttle will be turned off after a little increase, and it can start normally when it is started again, what's going on? Just removed the carburetor and cleaned it again and did not find that the main oil plunger hole was blocked, suspected that it may be the reason for the mixing ratio, tighten the mixing ratio screw clockwise and rotated counterclockwise about 3 times for a while, the gas pedal can be added, but when I put the removed saddle on and turned off, I thought it was too thin and twisted half a circle clockwise, and then the ignition will not work, the gas pedal will go out, the gas pedal will go out, I will adjust to the position just now, I am really angry. What is the reason for this?

Looking forward to the hero's help.
