When the scooter starts to stall while driving, it needs to be corrected as soon as possible. As a rule, this is not a serious breakdown and can be fixed without replacing spare parts. These problems are usually related to the spark plug and carburetor. So, why does the scooter stall while driving?!
This problem may be related to several parts. The reasons may be : spark plug, lack of gasoline and lack of air. We will look at why the scooter stalls while driving and then starts working again.
Cleaning and adjusting the carburetor
If you don't know why the scooter stalls when you give it gas, first check and adjust the carburetor.
If it was often removed and adjusted, it may be that somewhere it began to leak air. If such a problem occurs, you can use a sealant or buy gaskets for the carburetor. Let’s say the scooter stalls, you don’t know what to do. Then the first thing we do is clean the carburetor. Mostly the jets and auxiliary systems become clogged with dirt, so after cleaning the carburetor and adjusting all the jets, you can try to start the scooter again and give it gas. If the problem is not solved, move on to the main action - adjusting the needle to adjust the quality of the mixture. The needle in the carburetor performs the main task - adjusting the amount of fuel that is then supplied to the combustion chamber. Basically, you can adjust the quality of the mixture using a special jet on the carburetor, but if working with it does not produce results, you will have to manipulate the needle.
The needle is in close contact with the throttle handle, so when the handle is opened, the needle rises up and allows fuel to be supplied. That is, the higher the needle is raised, the more gasoline flows in and the power increases. Power guarantees better speed and traction. If you disassembled the carburetor, taking out the needle you will see 5 grooves on it, one of which has a retaining ring installed. Typically, such a ring is located in the center, that is, on the 3rd groove. If you lift the locking ring up, the needle will drop lower. This allows a leaner mixture to be supplied to the evaporation system, in which more air is supplied than gasoline. When installing the ring on the 4th and 5th grooves, the mixture becomes richer, where more gasoline is supplied than air.
Be careful that if you put the ring up or down as much as possible, this will not give the best result; the adjustment must be done gradually. Otherwise, the scooter will overheat, there will be a loss of power, and our main problem is that the scooter will stall when you press the gas handle. To find out the quality of the mixture, check the spark plug; its color will indicate whether the mixture is rich or lean.
Please note that there may also be other reasons why the scooter stalls when applying gas. Above we indicated the main ones; for some, the scooter stalls due to improper operation of the generator. Try, adjust, and share your problems and how to solve them.

Reason 3: electrical wiring
Sometimes owners notice that the reason when the scooter heats up and stalls is due to moisture getting into the devices or electrical wiring. In this case, the wiring is not able to function normally and, accordingly, produce a spark. The simplest thing you can do yourself is to simply dry the devices and wiring from moisture. It is also recommended to insulate the wiring with insulating tape; if all this does not help, then a more in-depth analysis of the electrical system is needed.

Does your scooter stall while driving?
Imagine the situation: you are riding a scooter, and suddenly it stalls and starts again. The reason is precisely the spark, or rather the peeling of carbon deposits from the electrode. When this action occurs, the scooter loses its spark and, accordingly, stalls. But when you move, the scooter operates at high speeds, which means the spark plug can clean itself of carbon deposits. The best way would be to replace the spark plug with a new one; its cost is quite low, but it will help solve this problem.

Honda dio 18 stopped starting

This means that lately the cold climate has been getting worse and worse. then it stopped even starting warm from the starter, sometimes it helped to kick it and then start it from the starter. the speed and acceleration seemed to be normal, then I was able to start it with difficulty with a kick from the 23rd time, and at that time it stalled at idle if I didn’t give it more gas. I decided to clean the carb, cleaned it, everything else didn’t help, I cleaned it now after completely disassembling it, washed everything completely and cleaned the jets and all the channels. I put everything together correctly, it won’t start - even though it cracked either from the kick or from the starter, I checked the spark - there is, and I also unscrewed the spark plug before after I cleaned the carb for the first time - it was covered in soot - I cleaned it and put it back - nothing has changed.
fuel is flowing, the fuel filter seems to be normal, but I have disconnected it from the line for now - still nothing helps, it won’t start and that’s it.
Tell me what to do next, unfortunately we don’t have any good craftsmen here. so we have to rely only on you.
No spark
To check the spark, apply ground to the spark plug.
- - faulty spark plug,
- — breakage of the spark plug or armored wire, short circuit in the ignition coil,
- - there is no contact or the diode in the ignition switch with three wires on diode 34 is faulty,
- — the switch, generator or hall sensor is faulty.
All this is checked with a multimeter, or, in simple terms, a “tseshka”.
Electrics is a voluminous topic, so I will describe it in another article.

There can be a lot of reasons. Spark plug, carburetor, vacuum fuel valve, CPG, valves, etc.
You unscrew the spark plug and see it’s black, wet and covered in soot. We replace it with a new one. If you have a compression gauge, we plug it in and turn it with the starter, see if the CPG is alive or if the valves are holding. The problem is not resolved, let's move on. Carb problem. We check the integrity of the membrane and blow it out. (don’t forget that the CVK carb and all pipes must be intact). We check the electrovalve enricher.

Because a Jap is worth fixing and driving. And it’s easier to throw away a Chinese car with the first breakdown. Here is a quote from the owner of a Honda Lead 50. And the 90s have even more resources.

I had a couple of Chinese. Now, if you'll excuse my French, I won't sit next to them to poop.
Honda had a tact - replaced the rings once and drove for five years without going anywhere beyond the filter. Lida is generally unkillable. The entire repair in three seasons was replacing the battery.
Preliminary inspection of a motorcycle Minsk
Everyone understands that for stable operation of a motorcycle engine it is necessary that the required amount of fuel enters the cylinder. It is also required that there is a good spark at the spark plug contacts.
If the Minsk motorcycle does not start, this means that fuel is not entering the combustion chamber or there is no spark. You should not rush to unscrew the spark plug or remove the carburetor, but rather listen to the opinion of experts who recommend starting to eliminate this problem with a simple inspection.
When inspecting a Minsk motorcycle, you need to check the following:
- the presence of gasoline leaks on the hoses and the engine, after making sure that the gas tank tap is open;
- presence of parts of damaged motorcycle electrical wiring.
If an inspection of the motorcycle does not reveal possible causes of the malfunction, then you need to move on to the next step.
Why the Ural motorcycle does not start - compression problems
Most often, the compression on a Ural motorcycle is too low. It does not pump gasoline into the cylinder, so the mixture does not ignite. There are many reasons for leaks:
- — Air comes out through the valve.
- — Air escapes through the gasket.
- — The air escapes through the rings.
It passes through the gasket - pour water on the ribs and there will be bubbles there. In this case, simply replace the gaskets with Ural. If not, take a syringe of engine oil, pour it into the cylinder, using a special agent. We plug it with our finger. Has the compression improved? This means that the answer to the question of why the Ural motorcycle does not start well must be looked for in the rings.
If not, unscrew the lid, first placing a lining under it. Notice that the valve is tightened, because the rod is pushed out a little, and they are not level. The one that is higher is clamped. To adjust the gap, you need to relax the valves both right and left. Gently press the valve with your foot. The valves are relaxed.
Check the gaps with feeler gauges. Find 0.05 mm and insert where the rocker arm connects to the valve. If it doesn't hold, the gap is too big. Let's look at the next one. Unscrew the bolts and take the dipstick. We clamp it between the valve and the rocker arm and tighten it slightly so that it holds the dipstick. Fix the bolt and tighten the nut.
Why does the scooter stall at idle?
A scooter, like any piece of equipment, can break down over time. Therefore, it needs to be checked and maintained from time to time. If the scooter is not serviced in a timely manner, it will therefore not serve you for a long time and faithfully. Even Chinese devices serve faithfully in capable hands. Today we will talk on the topic: “Why does the scooter stall at idle.”
Scooter stalls at idle
It happens that the scooter works well and picks up speed without problems. But if you release the throttle, the scooter will go into idle mode and stall. Most often this happens when it has not yet warmed up and without accelerating it stalls. But it happens that this happens after warming up or driving for a long time. What to do in such cases? Why does my scooter stall at idle? If it has not yet been run-in, then most likely you should just finish it and everything will work out. But if this is not related to the running-in, then we are looking for the reason.
Stalls at idle: reasons
The reason that the scooter stalls at idle may be a lean mixture (or a breakdown in the fuel system) or bad gasoline. Before starting repairs, check the quality of gasoline. If this starts after refueling, then you need to drain the gasoline and refuel at a proven gas station (you can rinse the tank with acetone). If this does not help, then you need to check the enricher itself and the mixture enrichment channels. If there are no problems there and the scooter stalls at idle, then we move on. We check the entire fuel system: - Carburetor. We remove and disassemble it. We completely wash every part and every channel. We put it back together in the same order as we took it apart. — Air filter. The paper one needs to be blown out with a compressor. If the condition is completely bad, then you need to replace the filter. We wash it with gasoline and dry it a little. Then soak it in oil. Squeeze out any excess glass in your hand. — Vacuum valve. Remove both hoses from the carburetor. We take the thin one into our mouth and suck it into ourselves. This is done to create a vacuum. At this time, gasoline should actively flow out from the other hose. If gasoline flows out sluggishly, you need to remove the vacuum seal and rinse, blow out, and clean it. After this, warm up the scooter well and adjust the idle speed.
If the scooter continues to stall at idle, then the possible reasons are: - The electric enrichment unit is jammed or incorrectly installed - The jets or the enrichment channel are poorly washed - The air filter is not sufficiently saturated or not saturated at all. — The carburetor is in poor condition. To check, you can tighten the quality screw completely and unscrew it one turn. This will be a very rough setting that will need to be reconfigured, but now you can check it will fix the scooter stalling at idle.

Reason 1: candle.
It is because of the spark plug that the most frequent breakdowns occur, when the scooter starts and stalls. There are electrodes on the spark plug, and when soot accumulates between them, the spark on the spark plug cannot work properly; in advanced cases, the spark does not pass through at all. If there is an incorrect gap, the spark plug will form a short circuit. This is what explains why the scooter stalls while driving - the spark does not come due to carbon deposits or a gap.
To avoid such malfunctions, we recommend monitoring the condition of the spark plug and, if possible, measuring the gap; this indicator should vary from 0.6 to 0.7 mm. At lower values, the spark plug will not work properly and will soon fail completely. If the gap is higher than these values, the spark plug will consume much more electricity, and the scooter's inability to produce this value will result in the inability to get a spark. Also, to avoid carbon deposits, we recommend sometimes driving at higher speeds, in which case the spark plug will clean itself. See in more detail here ⇒ why there is no spark on the scooter
