Stihl 250 Poor Minus Temperature

230 Stihl in its characteristics belongs to the class of semi-professional chainsaws designed for logging at a professional level (i.e., not just sawing wood in a bathhouse, but for example for sale).

Due to the ratio of size and power, the chainsaw is great for building from wood and felling trees. Due to the limited tire size, which is only 35-40 cm, the manufacturer recommends felling trees with a diameter of not more than 30 cm.

But, as practice shows, the Stihl 230 does an excellent job with larger trunks.

According to some reports, the engine displacement is 45.4 cubic centimeters. According to data from the official website of Stihl, the value of this technical specification is indicated by a range from 40.2 to 45.4. Therefore, in order to find out the real parameters of the Calm 230 engine, I recommend that you look at the passport for the chainsaw that comes with the package.

Options are standard. The price of 230 Calm includes the following items:

  • chainsaw;
  • tire and chain;
  • wrench for chain tensioning and oil and gasoline filling;

Features of the Stihl MC 230 chainsaw

230 Stihl, like many other company saws, are manufactured with the latest technology. Let’s see the main technologies used in the production of this chainsaw:

  1. Carburetor preheating. when working in the winter season, the chainsaw is switched to summer mode, the carburetor is blown with heated intake air, thus preventing icing.
  2. The innovative gas tank cap does not require a special key to open. Technology developed and patented by Stihl. The process of opening, closing takes place without difficulty, and the tightness, in turn, remains at its best.
  3. Anti-vibration system. Stihl, like Husqvarna, uses a special system to reduce the vibrations transmitted from the instrument to humans during operation. Without such a system, with prolonged work, the human body experiences heavy loads, which over time can lead to impaired blood circulation in the hands.
  4. Quickstop instantaneous chain stop. The well-known hand brake lever actuates the QuickStop mechanism, which allows you to instantly stop the work of the Stihl MC 230 chainsaw.
  5. Ematic chain effective lubrication system. The system includes an oil pump with variable oil flow, an Oilmatic chain and an Ematic guide rail. The peculiarity of the system is that the supplied oil reaches only those places where it is required, which allowed to reduce the oil consumption by half.

What is better stihl 180 or stihl 230

  1. The most important difference is that the Stihl MC 230 has a larger engine capacity, which in turn greatly increases the resource and, as a result, the service life.
  2. The Stihl 230 chainsaw is equipped with a heating system that prevents the carburetor from icing up when working in the winter season.
  3. The 230th is as much as 700 grams heavier than his younger brother. Believe me, when doing light work (pruning branches), this difference is significant.
  4. Therefore, the higher the price of the Stihl MS 230.

These are the main differences and they are important. Carefully weigh the pros and cons before choosing.

Carb adjustment

If the Stihl 230 chainsaw starts up and stalls or just works erratically, then it’s time to see how things are with the fuel supply system, namely the carburetor. Most likely the reason lies in him, and it requires maintenance.

Owner reviews

For me, buying a chainsaw was a real shock. Bought for 10 thousand rubles Stihl turned out to be a Chinese copy of the corporate tool.

I can’t say that the device is not working, but almost all the characteristics leave much to be desired. Significant costs are required to keep the saw in working condition.

Only last year’s fall season, we had to replace the starter, a headset with a drive sprocket, and a carburetor float.

Stihl 230 Chainsaw Carburetor Adjustment

Stihl 250 Chainsaw Adjustment

The stihl ms 180 chainsaws are designed in such a way as to greatly facilitate their operation by inexperienced users. To do this, some functions available on the more powerful Stihl models have been eliminated in the carburetor of the saw. But there is still the opportunity to set up, and the repair is also adjustment do-it-yourself carburetor chainsaw Stihl 180 possible.

When to adjust your Stihl 180 carburetor

To begin with, it’s worth deciding why, in general, you may need to adjust and repair the stihl ms 180 carburetor. So, you need to do this in the following cases:

  • if the chainsaw does not keep idle;
  • repairs may be required if the saw does not start;
  • there is a loss of power;
  • excessive fuel consumption;
  • chainsaw does not develop the largest momentum.
  • stalls at speed.

This list can be continued for a long time, but we have identified the main premises. Before proceeding with the adjustment, it is necessary to know what are the main parts of the carburetor on the Stihl 180 chainsaw, and who produces it.

So, the stihl ms 180 carburetor is designed and manufactured by a subsidiary of Stihl, under the name Zama. Photo and video. And carb adjustment. The Stihl 361 chainsaw is used. Unique carburetors on their case have a company logo guaranteeing product quality.

Fuel pump

A fuel pump is installed directly in the carburetor body, which operates under the influence of an air pulse from the crankcase of the chainsaw, transmitted through special channels. A diaphragm is installed in the pump; it is directly responsible for pumping fuel under the influence of an impulse. A gasket is installed between the diaphragm and the housing, which is responsible for the density of the fuel pump.

Distribution chamber

In the distribution chamber, as in the fuel pump, there is also a membrane that opens and regulates the fuel supply by pressing a special rocker, which lifts its needle valve with all this.

The chamber cover is the compensator case, which is mounted on the carburetor with 4 screws, a gasket is installed between the body and the cover, increasing the height of the chamber and responsible for sealing.

Nozzle

The fuel injector is integrated in the carburetor body in such a way that it is a connecting link between the distribution chamber and the cavity in which the throttle valve is installed. The fuel is supplied to the nozzle immediately with air and an air mixture arises.

The nozzle has a check valve that shuts off the air in the reverse order, in other words from the throttle chamber to the distribution chamber.

Throttle damper

A throttle is installed in the carburetor body and is responsible for increasing the supply of the fuel mixture directly to the engine cylinder. At the moment of pressing the gas, the throttle opens slightly, thereby increasing the channel capacity and fuel from the carburetor cavity, rushes into the cylinder in a larger volume.

Air damper

The carburetor air damper is installed on the reverse side of the throttle and is responsible for starting a cold motor, its control is carried out by the motor control lever.

The article describes in detail the adjustment of the carburetor of the chainsaw with three adjusting screws, as well as the adjustment of the carburetor of the Stihl 180 chainsaw with one screw.

For a cold start, the air damper is 100 percent closed, for normal operation open.

Adjustment carb stihl 180

The carburetor of the Stihl 180 chainsaw, indiscriminately, can only be adjusted by the number of revolutions at idle.

It is impossible to increase or decrease the fuel supply in various modes with the help of special screws. The manufacturer restricts access to adjustments and does not install these screws.

How to adjust the carburetor to the correct idle speed is very painstakingly described in the manufacturer’s instructions.

When certain flaws occur, and experience is available, increase or decrease fuel supply possible by increasing the gap when opening the needle valve.

For feed growth, rocker needle valve in the distribution chamber, it is necessary to bend up, and to reduce, down. This regulates the stroke of the needle and, accordingly, the throughput of the valve.

It is not necessary to carry out the adjustment without the help of others, because it must be done very accurately and if an error is returned, the initial position of the rocker arm is almost impossible.

Why the Stihl 180 carburetor overfills and some characteristic malfunctions

After we examined the carburetor device, finding the reason why the fuel enters the combustion chamber in a larger volume is not difficult. This happens due to wear on the gasket between the compensator cover and the carburetor body. You may ask how this can affect?

The answer is simple, shrinking, the gasket releases the diaphragm located on top of it a fraction of a mm down. She, in turn, will press harder on the rocker of the needle valve, it will open more than expected and the fuel will go in excess (begin to overflow).

Frequent breakdown of a Stihl carburetor and how to avoid it

A common cause of failure of a carburetor on a Stihl chainsaw is sticking of the valve in the nozzle. The cause of sticking is a violation of the storage of the chainsaw, or rather the manufacturer’s instructions Stihl 180 on proper preparation for storage.

As follows from the instructions, before long-term storage, it is necessary to drain the fuel from the tank, then start the saw and burn gas from the carburetor. Carburetor adjustment not needed chainsaw should the Stihl 180 chainsaw not start? Failure to comply with this usual rule has the following consequences.

The forsknui valve, being in certain contact with the fuel, sticks to the body, since gasoline gradually evaporates and only sticky oil remains. It is impossible to change the nozzle, because

they are not in the repair kit, you can only try to knock it out and rinse, which can not always be done without spoiling the nozzle.

Stihl 250 chainsaw carburetor adjustment and tuning

For the small, compact Stihl 250 chainsaw mechanism, proper carburetor tuning is key.

All coordinated work, all load conditions and its trouble-free operation directly depend on the adjustment of the fuel supply systems, the quality and quantity of the fuel-air mixture.

This article describes how to adjust the carburetor for the Stihl 250 and configure all of its dosing systems.

Carburetor device

In fig. 1 shows a modern carburetor for a German chainsaw manufactured by Stihl 250. It is a knot the size of half a human fist.

The manufacturer of the movement is Walbro, Taiwan. Case material. stainless steel alloy.

At the bottom of the device, a shutter is fixed, providing a uniform supply of the fuel-air mixture to the engine combustion chamber.

Fig. 1. Carburetor for the Stihl chainsaw.

Here, holes are made for attaching the assembly to the power unit housing. Between the flanges of the mixture supply and the combustion chamber of the engine, a gasket is installed. An accelerator pump is located under the throttle rod. It is a small piston with a rubber ring.

On the front of the case is a series of easy-to-use spring-loaded adjusting screws:

  • idle move;
  • maximum speed;
  • amount of mixture;
  • mixture quality.

The carburetor of the Stihl chainsaw is adjusted with these screws.

The main innovative feature of the carburetor for the Stihl 250 chainsaw is the heating device. In order to avoid freezing of the mechanism during operation during the winter period, it is equipped with a special system that preheats the steel case during operation. For this, the unit is switched to winter operation.

The body is blown with heated air drawn in from the engine. This mode of operation of the mechanism prevents icing, freezing of the nozzles, provides a normal flow of the fuel-air mixture. When switching to summer operation, the hot air damper closes. Summer mode is characterized by natural cooling of the unit.

Features of the Stihl 250 chainsaw

Need adjustment

Throughout the operation process, the need periodically arises for additional adjustment and ensuring the correct supply of the fuel-air mixture.

How to determine exactly when and what kind of adjustment is necessary for the normal functioning of the equipment? There are characteristic signs when the mechanism, by the behavior of individual parts, itself suggests when adjustment is necessary.

First of all, each time before the next engine start, it is necessary to check the color of the spark plug electrodes.

By changing it, you can decide on the need for adjustment, adjustment of work processes, improving the quality of the combustible mixture:

  1. Black electrodes coated with soot or soot indicate a re-enriched air-fuel mixture entering the engine.
  2. Brick-gray electrodes indicate that the mixture is perfect in composition and no additional adjustments are required.
  3. White plaque on the candle electrodes indicates that the mixture is lean.

The signs described in paragraphs 1 and 3 indicate that carburetor adjustment is essential for the Stihl 250 chainsaw.

Preparing for carb adjustment

Of paramount importance when setting all the fuel metering characteristics of the Stihl 250 is the top-most adjusting screw located near the muffler. The factory setting, the parameters of which are shown on the upper plastic cover, provides that it must be twisted one revolution from a full twist.

Do-it-yourself Stihl 250 chainsaw carburetor adjustment is carried out throughout the operation process. Unscrewing the screw enriches the working mixture, since the air-fuel mixture receives a larger volume of gasoline, and twisting the screw depletes the working mixture, since the air-fuel mixture receives less gasoline.

Adjustment of the carburetor will not give positive results if air intake from the engine side takes place through:

  • carburetor gasket;
  • accelerator pump rubber ring;
  • crankshaft oil seals.

Setting up the Stihl 250 carburetor is carried out only after a careful inspection, identifying the existing air leaks. The next stage of preparatory commissioning is the full maintenance of all components and mechanisms.

  • cleaning from deposits, slags, resins;
  • engine wash using solvent, acetone;
  • spark plug replacement;
  • cleaning, washing the air filter;
  • checking the tension of the cutting chain;
  • idle setting;
  • engine warming up to operating temperature.

Then you can proceed to complex manipulation settings.

Step-by-step adjustment of the Stihl МС 250 carburetor with a rev counter is carried out in the following sequence:

  1. Switch off the engine, tighten the screws H and L all the way, then unscrew both by one turn.
  2. Start the engine, warm up. At maximum speeds with screw H, achieve a maximum crankshaft frequency of 14,000 rpm, fixed by a tachometer or engine speed counter. Keep maximum engine speeds for no more than 10 seconds.
  3. Use the idle bolt LA to start the chain. After that, turn the bolt LA ¼ turn counterclockwise.
  4. Check the acceleration of the Stihl 250 chainsaw mechanism. Carburettor adjustment continues if the idle speed is unstable or the chainsaw is not accelerated enough. Screw L must be turned slightly counterclockwise. At the same time, the saw should quickly gain momentum, steadily function at idle. Finally, correct the operation with the LA screw. According to the tachometer, the idle speed should correspond to the catalog value of 2800 rpm.

Repair and maintenance of a chainsaw Stihl МС 230

Question: The Stihl ms 230 chainsaw, after replacing bearings, oil seals on the crankshaft, grabs but does not start, and it hits your hand very hard! Answer: The ignition system is faulty. Question: I did a piston replacement on a Stihl 230 chainsaw. Everything was assembled, nothing was left unnecessary, and when it came time to start only smoke through the exhaust.

Then a few pops in the carburetor and no longer start. Later I dismantled it again, missed the motor connection with sealant. After 2 days, almost the first time it wound up, it died out, later it grabbed a couple of times and does not start again. What could you miss? the spark is good, I tried 5 candles. I think the piston is correct, but the rings are not clear.

each cut in the opposite direction, and where exactly it looks without a clue. Must go along the axis of the shaft. Answer: Both cuts should be facing the carburetor, one on one side of the carburetor, the other cut on the other side of the carburetor, that is, the approximate angle between the cuts is 90 degrees. Question: Ask for supplies.

How many original driving sprockets and tires pass during the operation of a Stihl ms 230 chainsaw?

Answer: I think that the resource of the leading sprocket of any chainsaw in comparison with the Stihl 230 will be approximately the same. If the stars are not defective, then the normal resource will be unique.

It should be noted the convenience of replacing the drive sprocket on calm 230 (the user himself is calm 230). It is removed elementarily. The resource of calm tires is good. In work I use only Stihl tires and Oregon.

Question: What else needs to be changed while replacing a candle in a chainsaw? I saw a sealed piston and talked about a candle (and detonation) I understood, so that a spark happens, it doesn’t work and there are more powerful flashes in ICE, right? Answer: Candle and detonation are not particularly related.

A burnt piston and a failed candle can be from poor-quality fuel, but in no case one from the other. Candles, most often, work on failure. Very rarely. they are buggy.

Question: I have such a problem, the Stihl 230 chainsaw. It starts up well in the cold, having worked at idle for 1-2 minutes (it can work longer, maybe less), it stalls.

The candle is new, the filter is clean, the breather in the tank is clean, the compression is good, I sin on the ignition module.

Can someone tell me what the problem may be? The carburetor is clean. Answer: 1-2 minutes idling is a bit too much. it may appear on the electrodes for 20-30 seconds to warm up enough for now just try to add idle speed, look at the muffler Question: My ear has broken off on a Stihl ms 230 chainsaw , there is a cylinder from the 250th, can it be installed on 230? Answer: The cylinder mount is suitable, only there will be a change in power. But if the saw is old, and the cylinder is new (different release date) then it will not work. Different piston diameters. Question: A Stihl 230 saw was used in operation. After you plug it, gasoline flows from the carburetor. And it pours decently. What is the reason? The carburetor washed, blew. The needle valve is normal. Answer: Remove the carburetor and apply approximately 0.3 kg of pressure to the nipple (onto which the fuel hose fits). This pressure should not be relieved. At all. You can even 0.5 kg / sq. Cm, and the needle should hold it. If poison, repair the needle valve. The beam can get stuck on the axis, the needle may hang in the shaft, the needle itself may not hold. Question: Tell me, please, who knows how to start (pull the starter) Stihl ms 230 chainsaw? Answer: we select the free movement of the cord (until the dogs come into engagement with the flywheel) then we jerked and started. And then gently lower the launch cord to its original position, but do not unclench your fist and the cord is unwound itself, or in this case the starter breaks (for some reason, it is especially critical for calm). Yes, the jerk should be smooth and not very long. Question: I read that for uniform sprocket wear, change the chains with each new operation of the Stihl ms 230 chainsaw. Is it independent that the first chain is still very sharp? Answer: Chains from a set of chains change in turn as they become dull, are used cyclically, one after another, so that as a result, the total operating time of each chain from the set is approximately the same with the others. Then sawing will always be carried out by a sharp chain, and the wear of the chains will be approximately the same. Yes, and it is more convenient to replace the chains themselves when the chains are stretched approximately the same way. you do not need to turn the tensioner screw almost half its length each time, one way, then the other. Question: Do I need to turn the tire over each time, not often sawing with one chain? Answer: Turn the tire over. every time you change or sharpen the chain. Question: I bought a Stihl MC 230 saw, it starts up normally (the first time), but it was already barely started twice. it came to the point that gasoline was dripping from the muffler, the candle was wet. Maybe there is no spark, change the candle? or can there be many reasons? Answer: Put the lever in the first position from below, pulled 3-4 times, if there is a flash well, no, do not try to pull again, you will flood it. Translate in the second position and make a launch. If you still fill it in: Unscrew the candle and dry it. Turn off (ignition). We start the starter of races 15 ventilating the combustion chamber. After we screw in the candle and start from the second position from the bottom. Since there is already gasoline in the carburetor, it does not need a suction. Or we put the lever in the working position, hold the gas button and start. Question: About loosening the chain on a Stihl ms 230 chainsaw. if I easily wind it back and forth with 2 fingers, is it still better to loosen it? It’s just not so convenient, you need to unscrew 2 nuts, remove the cover, then twist the tension bolt. Can’t it be twisted without removing the cover and without unscrewing the 2 main nuts of the cover holding the tire? Answer: the cover does not need to be removed, the nuts are loosened and adjusted. Then, while tightening these nuts, lift the toe of the tire to the top. Question: what often breaks on the Stihl saw. piston? How much is the new, original? Really, only replace it and continue to cut it? Answer: The crankshaft oil seals fail, well, the piston wears out. Both that and another it is real to change even to itself and to work quietly further. Original, it is clear that dear. Question: On the new Stihl 230 saw, before starting operation, is it necessary to remove the drive sprocket and lubricate the bearing under it, or is there always enough lubrication? Well, maybe something else needs to be lubricated (tightened) before the start of operation of a new saw? Answer: Factory grease is enough for you until the next sprocket change. You do not need to twist and lubricate, we fill, start and saw. Question: Is it possible to put a larger tire on a Stihl 230 chainsaw? Answer: On the MS230 (according to official figures), you can use a bus with a maximum length of 45 cm.
