STIHL MS-660: How to tell a fake from a real one?

In the Russian Federation, authorized dealers are the exclusive dealers for authorized STIHL products. This means that you cannot buy an original STIHL saw in spontaneous markets or from dubious dealers. Official representatives have a certificate, made in gray, which must be provided at the first request of the buyer.

The tool has a serial number sticker that is duplicated on the plastic housing under the muffler. This index is also found on the packing box. All three numbers must match.

There is one large hole on the tire. Counterfeit models often have a small additional oil reservoir for lubrication. However, this is a deception. Manufacturers of the original modification provided for the lubricator with a reserve of oil, which is sufficient for the entire period of use.

Also, the standard chain has an S on each link, unlike the fake copies. The original model uses a minimum of stickers (available on the handle, where the safety instructions are prescribed). The basic STIHL logo cannot be glued.

READ STIHL 180 Saw Doesn’t Revolve

STIHL MS 180 chainsaw C1Q-S152E carburetor. 11301200608

The carburetor has a rigid nozzle instead of the maximum speed adjustment screw (H-screw).

The maximum speed is therefore theoretically set and cannot be adjusted.

It is only possible to adjust the idling speed within narrow limits.

The carburetor provides the optimum mixture under all operating conditions.

1.2 Standard carburetor settings for the STIHL MS 180 chain saw

If the carburettor must be readjusted, the standard setting must first be made.

L = Adjust the no-load speed setting screw (1) carefully clockwise until it is firmly seated, then turn one turn anticlockwise.

1.3 Adjusting the carburetor on the STIHL MS 180 chain saw

After each adjustment of the L = no-load speed regulation screw, at least readjustment of the LA = no-load stop screw (2) is necessary.

Note: Turn the screws only slightly and carefully. already a slight twist causes a noticeable change in the engine performance.

1.4 STIHL MS 180 chain saw engine stops when idling?

LA = Turn the adjusting screw for idle speed clockwise until the saw chain moves together. and then turn it back a quarter turn.

Stihl Chainsaw Carburetor Adjustment

LA = Turn the no-load adjustment screw counterclockwise until the saw chain stops and then turn it in the same direction by about 1/2 turn

Uneven RPM when idling, poor acceleration. although the speed regulation screw has been turned back by 1 turn

The mixture is not enriched enough when idling.

L = Turn the no-load speed regulation screw counterclockwise until the engine runs smoothly and with good acceleration

Diaphragm pump draws fuel from the fuel tank and delivers it to the carburettor.

The fuel filter on the STIHL MS 180 chain saw retains particles of dirt that enter the fuel tank with the fuel.

This results in the fine pores of the filter becoming clogged over time with minute particles of dirt.

The inlet opening is thus narrowed and the fuel supply is no longer adequate.

In the event of malfunctions in the fuel system, the fuel tank and fuel filter must always be checked first.

Clean the fuel tank, if necessary.

Replacing the carburetor on a STIHL MS 180 chain saw

If, however, the pressure drops, it is mainly due to two reasons:

Inlet needle valve is leaking (foreign particles in the valve seat, the locking cone of the inlet needle is damaged or the inlet adjusting lever is jammed).

In both cases the carburettor on the STIHL MS 180 chain saw needs to be repaired

Which carburetor is the right one for your STIHL MS 660 chain saw?

The STIHL MS 660 chain saw has a membrane-type carburetor and can therefore be operated upside down. The company has over half a century of chain saw history, so every part is state-of-the-art.

Unlike most other makes, non-original products have an identical design.

The STIHL MS 660 is one of the most powerful chainsaws in the world (7.1 liters).с.), professional grade.

That’s why the carburetor on it has an increased capacity, sufficient for this engine volume, and reliability.

Tuning procedure

Experienced operators may notice in the process that the chainsaw’s engine is starting to run worse. Sometimes it is enough to turn the screws H and L alternately to one side or another by a small step of 1/5. 1/6 of a turn and immediately check the result of carburetor adjustment in real operation. This is one of the simple ways to achieve a good adjustment.

What you need for adjustment

To access the adjustment, simply remove the upper housing cover and the air filter. So the only tool you need is a screwdriver for the slits of the adjusting screws.

An electronic tachometer is needed for professional carburetor adjustment. It accurately indicates idle and maximum rpm. The STIHL MS 660 chain saw has an idle speed of 2,500 rpm and a maximum speed of 13,000 rpm.

Without a tachometer, the quality of carburetor adjustment is determined by hearing and by the real performance of the chainsaw engine.

Standard or basic adjustment

Screws H and L clockwise all the way in, counting the number of revolutions made. Record or store the number of revolutions. If, as a result of an unsuccessful adjustment of the carburetor can not start the engine, this data will allow you to return to the original parameters of the factory setting.

  • Loosen screws H and L counterclockwise, each by 1 turn.
  • Start the engine and check its work by ear or tachometer.
  • If the rpm fails (suffocates) when you press the throttle trigger, unscrew the H screw another 1/4 turn.
  • if the engine idles while pressing the throttle trigger, tighten the screw L by 1/4 turn.

Every STIHL MS 660 chain saw has its own distinctive characteristics after it has been in operation for some time, including the compression ratio in the cylinder. That’s why the adjustment is individual. by turning the H and L screws in 1/4 to 1/3 turn in either direction you can get the chainsaw engine to work at the medium and maximum rpm.

Idle speed adjustment

needed if engine stalls at idle. low rpm or chain slips. high rpm.

To reduce the RPM, turn the LA screw counterclockwise until the chain stops, then turn it back a full 1/5th to 1/4th of a turn.

Adjustment of the LA screw is almost always required after adjusting the L screw, which also changes the engine parameters at idle.

The LA and L screws adjust idle speeds in basically different ways. L changes the quality and quantity of fuel delivery through the calibrated holes. The LA is called a “backstop” because it affects the position of the throttle, at idle speed.


A chainsaw carburetor is a part of a chainsaw’s fuel system designed to mist-mix gasoline with air and dispense that fuel mixture into the engine cylinder.

Note: The chainsaw carburetor mixes gasoline with air in a 1:14 ratio, t.е. gasoline and oil mix 1 part with 14 parts air, and adjusting your chainsaw carburetor ensures that it has the correct ratio of these components in the fuel mixture.
