The Lawn Mower Starts And Stalls

Pours candle on lawn mowers

It starts well on a cold one, but if you work a little and if you drown it and immediately start it up. The plug is constantly wet and began to throw the fuel mixture into the air filter. A similar breakdown My second channel, almost every day.

The Lawn Mower Starts And Stalls

Fills a chainsaw candle

Filled with gasoline and oil, the oil was a little more than the position. And in the morning I wanted to start, and the piston seemed to be holding something, scrolling the jerk. And when I put the candle on, the piston in the cylinder head starts to slow down, it goes tight and jerkily. I disassembled the cylinder head and removed the piston, there was carbon deposits from the excess oil on the piston head and the cylinder head. Write on the case here.

Chinese lawn mower won’t start.

When disconnecting the power take-off shaft, I start everything works fine! I connect it again, it hardly starts and stalls, or maybe it won’t start at all! Spare parts for Chinese lawn mowers The Chinese lawn mower will not start. It is interesting.

The lawn mower will not start.

A cold trimmer engine with a closed carburetor air damper starts up almost normally, runs at high idle speeds, when the engine heats up, an unstable operation is observed, after which the trimmer engine suddenly stalls. The lawn mower will not start.

# 128295; Why is pouring a candle in a chainsaw.

If the new candle also does not produce a spark. The problem is a high-voltage conductor or a broken plug connection. Brief instructions for replacing membranes in a chainsaw carburetor.

Pours a candle on lawn mowers

The main thing when installing a spark plug. First, you need to turn the candle by hand for a few turns, and then take the key. If the candle went easily by hand, then it is installed correctly and can be wrapped with a tool (a candle wrench with a wrench). If the candle does not want to be twisted by hand, it is not worth tightening it with a wrench, since the candle has gone out of the thread and damage to the thread in the candle hole of the cylinder is inevitable and expensive repair of the trimmer engine will be needed. Looks like my first channel:.

Ways to eliminate breakage

By carburetor The following works are possible:

  • Cleaning and adjusting the fuel supply valve;
  • Similar work with a valve that releases exhaust gases and vapors (after fuel combustion);
  • Replacing the weaker spring on the inlet valve;
  • Restoring the tension of the carburetor cable;
  • Replacing the fuel suction hose, checking and tightening the loosening of the connection;
  • Change of rotary disc damper;.
  • Changing a faulty wire or ignition coil.

When gassing

You step on the gas. And the trimmer stops working, and does not develop momentum. Possible Supposed Cause:

  • The carburetor setting, which appears with increasing load on one drive, is out of order. After long periods of inactivity or when working in extreme conditions;
  • The fuel valve is clogged with deposits;
  • The carburetor cable is weakened and sagged;
  • Excessively stretched, possibly torn fuel hose;
  • The non-return valve (breather) was forgotten by deposits. Fuel DOES NOT enter the fuel tank.

Immediately after the start

The stalling of a lawn mower or trimmer immediately after the start is due to the following reasons:

  • Imbalance of previously adjusted valves;
  • Initially incorrect valve train setting;
  • Clogging of the fuel supply valve by deposits;
  • Worn or loose hose.

Due to the broken fuel injection algorithm, the lawn mower or trimmer vibrates strongly during operation.

With increasing speed

If the lawn mower (or trimmer) stalls when adding engine rpm. Check your device for the following:

  • Blockage or sticking of the valve built into the gas tank cap;
  • Violation of valve adjustment;
  • Malfunction of pistons and cylinders. From vibration during the work of the scythe or trimmer, accidental blows directly during the mowing session;
  • Violation of the supply of the air-fuel mixture;
  • Excessive pumping of air into the motor;
  • Cracking of the fuel inlet hose, loosening of its connections.

When the air-fuel mixture is supplied in the required portions to the engine out of time. The one burns the amount that has been received since the last stall, and itself stalls again.

Main reasons

Possible reasons for the lawn mower or trimmer to stall when trying to restart and resume interrupted work:

  • Engine problems;
  • Failure in the petrol and oil supply system;
  • Damage to pipelines (capillaries, hoses, nozzles)
  • Malfunctions in the ignition system.

A general description of scythe or trimmer problems is not enough here. A clear and immediate repair, high-quality service is impossible without specifying the identified cause.

With a similar problem, pay attention to the fuel valve, which, when clogged, stops passing the fuel mixture normally. The solution to this problem is to mitigate it with a suitable tool. In addition, a problem with the circulation of the fuel mixture may lie in the valve clogging. To do this, it is enough to blow it with a stream of compressed air.

At high revs

When the scythe stalls at high speeds, this is due to the following problems:

  • Clogged or sticking valve located on the gas tank cap;
  • The carburetor is out of alignment under the influence of vibrations arising from the operation of the mechanism;
  • Problems with the circulation of the fuel mixture;
  • Leakage of atmospheric air;
  • The fuel intake hose is cracked or loose.

Adjust the carburetor referring to the trimmer operating instructions. For adjustment, it is often enough to loosen the tightening of its body. If there are problematic points with the circulation of the fuel mixture, then it can gradually enter the carburetor. After its development, the engine stalls at high speeds.

Idle

At idle, common reasons for trim stopping are as follows:

  • Dirty, misaligned or incorrectly adjusted carburetor adjustment;
  • Clogged air filter;

Replacing the air filter for lawn mowers

  • Reducing the speed of the gearbox when it heats up, which is a consequence of using an unsuitable fuel mixture;
  • Clogged throttle;
  • Air ingress into the system;
  • Not enough fuel to operate the lawn mowers.

When you hit the gas

If the lawn mower stops when the throttle is pressed, the reasons may be as follows:.

  • The most common option. This is a malfunction of the carburetor adjustment, which occurs under significant loads on the drive, after prolonged inactivity of the mechanism or when it is used in difficult conditions.
  • Clogged fuel valve, which is eliminated by loosening it, as a result of which gasoline begins to flow normally through the system.
  • Loosening and drooping of the cable in the carburetor. The fuel hose may also stretch to the point of rupture due to a significant load.
  • Clogged breather (Check valve), as a result of which fuel does NOT enter the tank.

If the problem is with the carburettor assembly, the lawn mower vibrates to recognize it. When a hose bursts or a cable stretches. Replace these components.

What could have broken

Problems with the lawn mower, due to the fact that this device does not start, are classified in a certain way by service specialists. They highlight faults with the following components of the mechanism:

  • Engine, in which the piston and bearings may wear out or fail, crack the crankcase;
  • The fuel supply system, with the possible clogging of the filter or problems with the carburetor;
  • Mechanical damage to wires, tubes, hoses;
  • Ignition circuit.

Lawnmower Starts And Immediately Deafes Reason

The tool, in spite of its small dimensions, is a complex technical device. If you study the annotation for operation, it turns out that the prerequisites why the lawn mower does not start are known and removable. It is necessary to eliminate one by one the reasons that make it difficult to start the tool. Usually start with more accessible nodes with an easy health check.

What remains for our client to do the prerequisites, why the lawn mower does not start, of course, systematize according to the specifics of the work of SEPARATE units. In a car service, malfunctions are systematized:

The user first needs to check if there is fuel in the tank. The start-up is carried out in accordance with the annotations, put the dust on its side. Set the air damper to the “closed” position, pump up fuel, turn on the ignition and make 3-4 sharp jerks with the starter. If the engine is running, open the air damper. The lawn mower will not start. We repeat the operations with a slightly open air damper.

The lawn mower is not allowed to work for a long time. The gearbox and engine will overheat. Mowing is an option for less than 15 = 20 minutes, taking a five minute break. On a hot afternoon, working hours are cut in half. When mowing weeds, sedges, the working time must be reduced.
