The Benzotrimmer Does Not Idle

The benzotrimmer does not keep idling

The Lacetti 1.6 engine has an electronic throttle valve. maybe you need to reset adaptations.
It was so with me. swam revolutions. even went deaf on the move. drove off. everything became ideal

The car was idling and stalled and will not start

For example, the Chevrolet Lacetti stalled, the starter turns, but nothing helps. The reason is a malfunction of the mass air flow sensor, which needs to be replaced.

If engine stalls then starts normally

Such problems are consistently provoked by electronic equipment. The user should check errors in the BC, wiring, there may be malfunctions in relays and electronic units, sensors.

The car stalls at idle in a traffic jam

If a car stalls not in motion, but when it stands, most likely its owner had to face one of four problems:

  • overheating of the fuel pump;
  • failure of solenoid valves;
  • breakage of ignition wires;
  • voltage drop.

The easiest way to get rid of the malfunction in the latter case is to raise the speed to a thousand or more. The first reason is often found in Tavria and is characterized by the fact that the revolutions are floating. Pump needs to be replaced.

Interruptions in the operation of carburetor and diesel engines

Why do engine rpm float in carburetor machines? Unstable activity can be caused by the following reasons:

  • Failure of adjustments at idle modes.
  • Failure of the solenoid valve of the carburetor engine.
  • Excessive accumulation of combustion products in the jet.

Diesel motors have jumps and drops in the readings of the device during intermediate modes and when idling. In these cases, the diesel engine speed is said to be floating. This is due to rust formed on the impeller of the injection pump. Water in diesel fuel causes corrosion.

Consequences of unstable motor activity

All of the above reasons, working with engine interruptions, cause a number of negative consequences:

  • increased consumption of gasoline or diesel fuel;
  • environmental pollution by exhaust gases containing an increased percentage of harmful gases;
  • increased wear of units and parts of the power unit.

The idle speed regulator is out of order

The problem is common to injectors and modern internal combustion engines. The smart unit often fails due to mechanical damage, normal wear and tear or incorrect calibration.

The electronic regulator has several weak points:

  • signal sensors;
  • control relays;
  • fuse system.

The origin of interruptions in the speed of the injection engine

Injection-type vehicles are especially susceptible to instability in engine idling. Uneven functioning occurs for the following reasons:

  • Excess air in the cylinders.
  • Breakage of the idle speed regulator (IAC).
  • Oil crankcase ventilation valve failure.
  • Malfunction of the crankcase mass air flow sensor (DMRV).
  • Throttle body stuck.

Engine troit and stalls at idle

For example, Mitsubishi Lancer 9 tries to start, but the engine starts to triple and turns off, most likely the coils, candles or crankshaft are to blame. To fix the problem, you should contact the car service.

Symptom: too high idle rpm

There may be several problems.

  • The throttle valve wedges, the valve does not close to the desired position and too much fuel comes in.
  • A short in the fuel pump line, forcing it to work at high speeds.
  • The wrong jet is installed in the carburetor with an increased cross section.
  • Gas pedal sinks.

A small amount of oil gets into the turbine.

What to do if the chainsaw is gaining momentum by itself?

This malfunction is typical for novice gardeners who ignore the need for timely maintenance of their gas powered tools. In the case of an arbitrary set of revolutions with a chainsaw, the cause must be sought in the carburetor. First of all, it will need to be completely disassembled. After making sure that all the built-in parts are in good working order, you can start flushing the fuel unit. For this you need:

  • place all carburetor elements in a container with clean gasoline. After knocking, the parts must be removed, rinsed thoroughly with water and dried;
  • the fuel pipes must be blown out with compressed air from a cylinder. Immediately before re-installing the hoses in the places where they are connected to the fittings, you will need to apply silicone sealant;
  • after installing the carburetor, not the chainsaw, you need to re-adjust it. Before that, you need to make sure that the power unit is in good condition, as well as the filters, rubber gaskets and bushings are in working order.

In some cases, the cause of an arbitrary set of revolutions with a chainsaw may be a loss of sealing of the crankshaft oil seal. Due to constant contact with the moving shaft, the stuffing box lends itself to increased heating, which leads to the formation of cracks and holes inside it. A damaged gasket cannot be repaired, so it must be replaced.

Often the cause of air leakage, due to which an arbitrary set of revolutions by the motor occurs, is the loss of fixation of the bolted connections. In this case, the operator will need to tighten all the bolts and check the operation of the gasoline tool again.

Does not idle the chainsaw

The serviceability and efficiency of household and professional chainsaws largely depend on the degree of wear of their main operating mechanisms. Several factors indicate damage to the working units of the gasoline tool, the main of which is the speed of the running engine. Their arbitrary growth or decrease can prompt the operator about a breakdown of the carburetor, violation of the clutch clearance and other malfunctions. this will make it possible to identify any of the breakdowns in time and eliminate it on their own.

The chainsaw does not slow down. how to find and fix a breakdown?

The most common cause of this frequent breakdown is an incorrectly adjusted damper. It is necessary to suck in the air that the carburetor needs to enrich the fuel mixture with air. To adjust the choke, you need to adjust the operation of the carburetor. In this case, special attention must be paid to the operation of the power unit at idle. You can check the operation of the engine in idle mode by paying attention to the state of the circuit immediately after starting the engine. If it rotates, then you need to adjust the power unit.

Another reason for this typical malfunction is air leaks. If air leaks in one of the chainsaw mechanisms, the mixture will automatically deplete, which will lead to a spontaneous increase in the speed of the chainsaw motor. In this case, the operator will need to carefully check the entire fuel system, including the carburetor, pipes, and working chambers of the unit.

In some cases, the chainsaw does not decelerate due to a jammed accelerator cable. In this case, the power unit will independently gain momentum to the maximum immediately after it is started. Disassembling the gas handle and inspecting the entire gas supply mechanism will help solve the problem. A jammed cable will need to be adjusted or completely replaced.

Why the chainsaw isn’t picking up speed?

In cases in which the used gasoline saw is not able to steadily gain momentum and stalls spontaneously when you press the accelerator, you will need to carefully check the engine crankcase and carburetor. First and foremost, the operator should carefully inspect the assemblies to ensure they are not sealed. If a large amount of oil was found inside the crankcase or carburetor, then it is necessary to repair the leak inside the faulty unit.

The next reason why the chainsaw does not develop speed. a manufacturing defect or mechanical damage to the breather located inside the fuel tank. A vacuum can form in the fuel tank, which leads to a lack of fuel supply to the working cylinder of the power unit. Deposits that have accumulated on the surface of the fuel cylinder can also cause this problem. In this case, you need to remove the filter element and rinse it in clean gasoline. If after that the chainsaw continues to stall under load. then you need to perform the following procedure: turn off the power unit of the chainsaw, remove the fuel tank cap and tighten it again. If after that the motor of the gasoline tool starts to gain momentum and after 5 minutes of operation it stalls again, then the cause of the breakdown is a faulty breather.

A thick layer of carbon deposits on the walls of a factory muffler can be another common cause of a saw motor not rotating. Resinous deposits and ash will prevent exhaust gases from escaping, which will lead them back to the engine compartment. As a result, the engine will begin to emit extraneous sounds and greatly lose speed even with a slight press on the accelerator.

The chainsaw does not idle. search for reasons and repair

There can be several reasons for this common breakdown. Basically, the loss of speed when the internal combustion engine is idling is associated with engine malfunctions, loss of compression in its standard cylinder, ignition system, carburetor, as well as improperly prepared fuel mixture. In search of the exact cause of a breakdown, the operator may encounter the following problems:

  • accumulation of resinous deposits and ash, small debris on the air and fuel filters of the chainsaw. if possible, the elements must be washed. If, in addition to blockages, cracks or holes were found on the surface of the filters, then the foam rubber elements will need to be completely replaced;
  • spark plug defect. cracks, chips or burrs disrupt the work of the part, which leads to a loss of engine speed when the engine is idling. In this case, the candle will need to be replaced;
  • loss of factory settings of the carburetor. increased pressure on the power unit leads to an increase in its vibration. As a result, the spring-loaded metal bolts of the fuel assembly lose their original position, which leads to a loss of engine speed;
  • cracks and holes in the fuel pipe. to repair the chainsaw, the hose must be replaced;
  • clogging of the inner walls of the muffler. dismantling, thorough flushing and reinstalling the muffler will help solve the problem. If large burrs have formed on the internal cavities of the element, then it will soon begin to rust. To prevent this, it is better to replace the muffler immediately;
  • malfunction of the CPG of the power unit. the appearance of microcracks or burrs on the inner surface of the cylinder and piston will lead to a loss of tightness of the working chambers. As a result, the amount of air required to enrich the fuel mixture will be disrupted. this will result in a loss of engine speed when idling.

The stable operation of a chainsaw engine largely depends on the quality and proportion in which the fuel mixture is prepared. An excess or lack of oil will lead to a gradual deterioration in the operation of the power unit and over time it will not be able to work even at idle speed. To prevent this, you must strictly adhere to the ratio of gasoline and oil, which is indicated in the instructions for the chainsaw used.

Why the chainsaw isn’t picking up speed?

When starting the gasoline tool, almost all systems and components are involved. At startup, there may be problems with the speed, they can be provoked by the following reasons:

  • Engine malfunction due to depletion of service life, wear or deformation of piston rings and cylinder;
  • Coil or spark plug problems. no spark to ignite the fuel mixtures;
  • Unbalanced carburetor screws.

To test the ignition module, proceed as follows:

  • A candle is unscrewed;
  • Her condition is assessed. It is impossible for it to be filled with gasoline or there was a black coating;
  • The distance between the coil and the magnets is checked (up to 0.2 millimeters);
  • In addition, the spark plug unit can be checked for spark supply by a working network drive.

If the chainsaw does not develop further, it is worth testing the carburetor. Low and high speeds are set by default, they are reset after the running-in process and short-term use of the tool.

The turns are adjusted with screws, they are unscrewed to the stop. In this situation, it is necessary to reconfigure the H jumper, which is responsible for using the unit under load. Adjusts the flow of the fuel mixture while the engine is running at the highest chain speed. The tachometer and instructions from the manufacturer will help you to configure.

The chainsaw does not slow down

In some cases, the petrol tool quickly reaches a certain power level and does not slow down. To eliminate it, it is not enough to adjust the screws on the body or clean the carburetor. The essence of the problem is the high consumption of the fuel mixture.

The following steps are taken:

  • The serviceability of the throttle cable is checked;
  • The return spring is examined. it can jump off;
  • The rear flap must be completely sealed.

Chainsaw does not idle

The problem is quite common. The most common causes of misbehavior when starting and spinning the chain are:

  • Clogged air and fuel filters;
  • Low-quality fuel is used or the fuel mixture is incorrectly prepared;
  • Problems with the ignition module;
  • Carburettor block settings do not match the load level;
  • Deformation or rusting of engine components.

Algorithm of actions:

  • The fuel hose is thoroughly flushed or replaced;
  • The air filter is cleaned of all contaminants. The reusability of the filters allows them to be removed and cleaned with detergents;
  • Fuel and oil are checked for quality. It is better to use the mixtures specified by the manufacturer in the instructions;
  • Carburetor block and plugs are tested.

Often the problem is with only one part. After its elimination, the unit can be actively operated again.

Chainsaw revolutions

Modern chainsaws are characterized by rather complex designs and simple operation. Regardless of the features of the tool, it is not insured against breakdowns. Almost all malfunctions can be avoided with proper care and use of technology.

Problems that the operator may encounter when working with a petrol power tool:

  • Not gaining momentum;
  • Idling turns do not hold;
  • Turnovers are not thrown off;
  • Turnovers pick up themselves.

In some cases, it is worth using the services of a specialist from a service center. But these problems can be eliminated by hand.

The chainsaw picks up speed by itself

A problem may arise when the saw itself starts to gain momentum. While working, the unit stalls, not allowing full use of the chainsaw.

Factors that can provoke the failure of the unit:

  • Clogged carburetor, fuel or air filters;
  • The fuel step is damaged or clogged;
  • The leading pipe between the carburetor block and the engine cylinder is depressurized;
  • Problem with setting the propeller (often H-propeller) of the carburetor.

The following works are carried out:

  • The carburetor and filters are cleaned. In this case, the correct adjustment of the screws L and H is controlled;
  • The fuel filter should not be removed as this will adversely affect the tool life. It is enough to check if it is ignited, the fuel supply hose should not be bent.

Problems with the working speed of the chainsaw can arise in any situation. Therefore, it is important to be attentive to the gasoline tool, to carry out maintenance and diagnostics on time. Correct and timely work will quickly restore the saw’s working functions.

The scooter does not idle and stalls

The scooter does not idle. the main reasons

Consider a situation where the scooter starts but does not idle. The engine strives to stall.

Of course, this is a clear sign of piston wear and a catastrophic drop in compression, so you first need to make sure the engine is in good working order. In general, any troubleshooting with the engine, you need to start with measuring the compression. If the piston is worn out, you will never be able to carry out high-quality diagnostics and restore normal engine performance.

It should be noted that further we are not considering floating idle, namely the impossibility of the scooter idling after starting. That is, when the scooter starts up, it will idle a little (even if it is 2 seconds) and stalls. If the rpm floats, but the engine does not stall, this is the place for you. why idle rpm float.

Doing This Will Make Your Car Idle Better

Now, in fact, the reasons.

Why the scooter does not idle and stalls

  • Check the screws for mixture quality and idle speed. The quality screw should be unscrewed 1.5 turns and the idle screw to normal speed. at the same time, the engine should respond well to idle speed adjustments by increasing and decreasing rpm.
    Oddly enough, but in most cases, when scooters come to our workshop with a complaint. “does not keep idling”, we just make adjustments using screws for 1 minute and the problem is solved.
    Important: the adjustment should be made only after the engine has warmed up, when the starting enrichment closes the channel, we talked in more detail about adjusting the carburetor here. how to properly adjust the carburetor.
  • Make sure the starter enrichment is working properly. Without its adequate work, the cold scooter engine will not keep idling. How to check it correctly, we considered here. checking the starting enrichment on a scooter.
  • If the compression is normal, and when adjusting the idle speed with the screw, there is no reaction from the engine, most likely dirt has got into the idle jet. The carburetor must be removed and cleaned. It is important to do this correctly, by unscrewing the nozzles and completely purging all channels. How to properly flush the carburetor, we discussed here. At the same time, check the starting enrichment.
  • Dirt could also get into the channel of the starting enrichment.
  • Check valve clearances if the scooter is four-stroke. How to do this correctly, we talked here. how to adjust the valves on a scooter.
  • Some Chinese switches can distort the ignition, then the engine also stalls, while it is extremely unstable for several seconds. If you have previously replaced the switch, pay attention to this.

Normal operation of a scooter at idle speed depends on many factors, including the condition of the piston, spark plug, carburetor, air filter, muffler, switch, hall sensor, etc.

To know for sure the cause of the unstable idling of your scooter, it is necessary to carry out a series of operations to identify the breakdown and make decisions for troubleshooting.

Let’s start checking. Adjust the idle speed of your scooter, watch what happens next. Let’s consider three possible developments of events point by point:

Even after tuning, the scooter engine runs at high revs. First, you need to make sure that the throttle valve on your scooter is fully closed to prevent gassing. If the damper is not fully closed, you need to check the adjustment of the gas control cable (damper) and adjust the cable properly.
However, if the throttle is closed, and the rpm is still high and cannot be adjusted, it is necessary to check the idle jet in the carburetor for compliance with the required marking, namely, the required diameter for a particular scooter model.
2. The scooter works unstable at idle, despite the manipulation of the setting. In this case, initially you need to check the ignition timing for compliance with the standards. If deviations are found, the switch, the hall sensor, the wiring must be checked.
If the ignition timing is normal, the first step is to pay attention to the gap between the spark plug electrodes. If the gap does not correspond to the nominal, it must be determined as such, and if the gap and the plug are normal, the composition and quality of the fuel mixture, regulated by the carburetor, must be checked.
3. The scooter does not idle despite numerous attempts to adjust the idle speed. In this case, the first thing to look at is compression. In the absence of normal compression, it is simply unrealistic to achieve a stable idle.
If the compression is found to be very low, make sure your scooter is tight, check all gaskets and bolt tightness. Check piston rings for wear.
If the compression is still normal, go to the idle jet. In such cases, it is often clogged with dirt, which means that cleaning the carburetor is simply necessary here.
Even if after cleaning the carburetor it is not possible to achieve idling of the scooter, be sure to check the fuel level in the float chamber and, if necessary, adjust.
In that case, if the problem has not been resolved, it is necessary to inspect the carburetor mount, making sure that there are no various damages. The vacuum tube of the fuel cock and the plate valve are also subject to inspection.

In this article, you will find answers to the following questions:
Why does a scooter stall at idle.
Why is there no idle on the scooter.

Briefly, the process of finding the cause of the lack of idling on a scooter can be observed in the following diagram:

As a rule, after all the considered manipulations, it is possible to restore the normal idling operation. Do not forget also about adjusting the valves on a four-stroke scooter, regularly checking the air filter and cleaning it in time.
