Frequent breakdown of the Stihl carburetor and how to avoid it

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

Stihl 230 semi-professional chainsaw review

According to its characteristics, 230 Stihl belongs to the class of semi-professional chainsaws designed for harvesting firewood 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 ideal 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 no more than 30 cm.But, as practice shows, the Stihl 230 copes well with larger trunks.

Features of the Stihl MC 230 chainsaw

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

  • Preheating the carburetor. when working in the winter season, the chainsaw is switched to summer mode, the carburetor is blown by heated intake air, thus preventing its icing.
  • The innovative gas cap does not require a special key to open. The technology is developed and patented by Stihl. The process of opening, closing takes place without difficulty, and the tightness, in turn, remains at a height.
  • Anti-vibration system. Stihl, like Husqvarna, use a special system to reduce vibrations transmitted from the tool to the person during operation. Without such a system, during prolonged work, the human body experiences great stress, which over time can lead to impaired blood circulation in the hands.
  • Instant chain stop with QuickStop brake. The well-known handbrake lever activates the QuickStop mechanism, which allows you to stop the Stihl MC 230 chainsaw with lightning speed.
  • Efficient chain lubrication system Ematic. The system includes a variable oil pump, Oilmatic chain and Ematic guide bar. The peculiarity of the system is that the supplied oil reaches only those places where it is required, which made it possible to reduce the oil consumption by half.

According to data from the official website of the Stihl company, the value of this technical characteristic is indicated in the range from 40.2 to 45.4. Therefore, to find out the real parameters of the 230 Calm engine, I recommend looking at the passport for the chainsaw, which comes with.

READ  Stihl No Oil Served On A Chain

The package is standard. The cost of 230 Calm includes the following items:

  • Chainsaw;
  • Tire and chain;
  • Screwdriver wrench for tensioning the chain and refueling oil and gasoline;

Chainsaw carburetor adjustment

Most chainsaw carburetors have three adjustment screws:

  • L. jet screw for adjusting low speed
  • H. jet screw for high speed adjustment
  • Screw. T at Partner and Husqvarna (at Calm LA). adjusting the idle speed of the chainsaw

Screws H and L adjust the ratio of the mixture of gasoline and air, determined by opening the throttle valve of the carburetor. When the screws are unscrewed, the mixture is enriched, and the revolutions increase accordingly, when the screws are tightened, the mixture becomes leaner. the revolutions fall.

The screw T (LA) is designed to adjust the idle speed. The basic "tuning" of the chainsaw is done at the factory during final testing. The carburetor is usually adjusted for a richer (than optimal) fuel mixture. The factory setting must be maintained during the first hours of saw operation. Then (optional) a more precise carburetor adjustment is made.

We begin the adjustment by setting the idle speed, for this we turn the screw T (LA) counterclockwise, achieving a complete stop of the chain at stable engine speeds.

For further fine adjustment, you need a tachometer and it is better to entrust it to specialists, especially since in most cases it may not be needed.

We start setting up the tool with the L screw, then use the H screw and finally the T screw (LA).

We find the highest idle speed, for this we slowly turn the screw L in different directions. After finding the position of the highest engine speed, turn the screw L 1/4 turn counterclockwise. If the chain rotates at idle speed, the screw T should be turned clockwise until it stops.

The screw H adjusts the power and speed. Adjusting the carburetor to a lean mixture leads to excessive speed, overheating of the engine and failure of the piston chainsaw.

We warm up the engine of the chainsaw at idle speed for at least 10 seconds and turn the screw H 1/4 turn counterclockwise. Let the engine run for about 10 seconds, then check the maximum engine speed with a tachometer. If the maximum speed does not match the passport, the operation should be repeated. When the mixture is too rich, the muffler starts to smoke, when the saw is too lean, it squeals and overheats.

We finish the adjustment by adjusting the idle speed, as already described above. The idle speed is set correctly if the engine runs smoothly at minimum speed and the chain does not rotate.

The carburetor can be considered adjusted if the engine accelerates quickly and sounds like a four-stroke at full throttle.
