Stihl : MS170 & MS260 Choke Adjustment

skwerl said:

Stihl got rid of the limiter caps??? How'd they manage that? The last 026 I owned had a fixed high speed jet (POS, PITA) and pretty much turned me off to Stihl for the time being.

They never had limiter caps on the 260... the carb was either the WT403 with no high screw, or the 426 (and a few others) with a semi-fixed high jet and a H screw - but you only get to vary about 10-15% of the gas flow which is usually enough.

I fix a lot of 026 / 260 and although my hand twitters toward the box of WT194 or WT 426 (2 adjustment screws) I'm surprised by how well the WT403 works for those that don't want (or need to want) the perfect H adjustment. It runs a tad rich, but usually Tach at 13,000+/- which is plenty for guys with a factory muffler and who want to cut wood without a stopwatch :D

On the other hand, I've sold a lot of WT194 / WT426 to AS members... (I'm OUT OF STOCK right now).

STARTING YOUR CHAINSAW

When cold, the correct starting technique is as follows:

1. Depress the throttle lock and throttle, and move the control lever to full choke (i.e. moved to the limit of its travel).

2. Firmly press the primer (if fitted) 2–3 times. It is impossible to over-prime as excess fuel is simply returned to the fuel tank.

3. Place the saw on the ground. With a firm grip (i.e. left hand on top handle and foot through rear handle) pull the starter cord 3–4 times, or until you hear the engine 'fire'. Note: Do not pull starter cord more the 3–4 times while on full choke to avoid engine flooding.

4. Once the saw has 'fired', move the choke up to the “half-choke” position and pull over. The saw should now start within 3 or 4 pulls

5. The first touch of the throttle will allow the choke to automatically move to the fully open position and the motor will idle.

Note: If the engine is warm, it is not necessary to commence the starting procedure on the full choke position. Instead, simply move the choke to the half-choke position before pulling over.

WHAT IS STIHL M-TRONIC?

STIHL M-TRONIC (M) is an internal feature on selected STIHL Chainsaws that regulates ignition timing and metering while taking into account external factors such as temperature and fuel quality. This allows for optimal performance, constant maximum speed, and excellent acceleration.

The simplified starting procedure on STIHL M-tronic models allows the machine to automatically cater for hot or cold starts - removing the risk of flooding. A cold start on a Chainsaw with STIHL M-Tronic requires just one start position on the combi-lever. Once started, you can power up to full speed right away.

WHAT IS STIHL ERGOSTART?

Internal combustion engines such as STIHL Chainsaws have compression pressure and as a consequence result in 'jerky' stresses. This is what you can feel during the starting process. STIHL Ergostart (E) relieves this jerking movement to make the experience far easier and smoother.

Ergostart works by tensioning an internal spring against the compression pressure when the starter cord is pulled. The energy stored in the tensioned spring is released onto the Chainsaw's crankshaft automatically to start it moving and thus avoids the jerky movement during starting. As a result, the starter cord is able to be pulled two-thirds slower than conventional Chainsaws.

How To Start a Stihl Weed Eater? | Pad Outdoor

Stihl is one of the best weed eater brands in the market for many years already. Its excellent reputation is rooted in the brand’s ability to produce heavy-duty and premium tools and machinery such as the weed eater or also known as weed trimmer.

Today, we will lay out the steps on how to start a Stihl weed eater and how to operate this machine properly.

But Stihl has produced dozens of trimmers. How do I know that I am following the correct start-up operation for my current model?

Yes, it is true that there are different Stihl weed eaters available, but all their starting methods are, more or less, similar. Of course, it is still best to refer to the specific instructions of your unit.

How To Start A Stihl Weed Eater (6 Steps)

Here’s a guide on how do you start a Stihl weed eater:

1. Inspect The Fuel Tank.

This is the first thing that you need to do. Inspecting the fuel tank means making sure you have enough fuel in the tank for the starting operation.

What happens if the fuel level is low?

This could lead to disruptions while starting the machine or hamper the starting process altogether.

This step is necessary for the gas Stihl weed eater models but not a problem for the electric models. If you are eager to know how to start a Stihl weed eater FSE 60, then you can worry no more. This model is an electric Stihl weed eater and you can just skip this step.

What’s the ideal gas to oil fuel mixture? Most Stihl gas-powered models make use of 50-to-1 gas-oil fuel ratio.

2. Clear The Area Within A 10-Meter Radius.

For safety purposes, it is necessary to follow this next step. Make sure that the area surrounding you is clear and there are no things that can easily catch fire.

Why do you need to do this? This is because the weed eater’s head will spin immediately once you start the machine. If, for instance, the trimmer line makes contact with a foreign object while spinning, this can cause an accident.

Also, make sure there is no other person within a close radius of 10-meters before you even start the weed eater machine.

3. Switch To “On” Position.

Press down and hold the throttle trigger interlock. In other models, this one is called the lockout lever.

Refer to the image below for guidance:

Squeeze the throttle trigger and switch the starter to “ON” position while still engaging both levers.

In gas-powered models, the “ON” position is indicated with a capital “I” while some models use the easier-to-read “Start” word. Also, other models require to turn over the engine first so that you can move the switch to the start position.

Once you’ve successfully done this, release the pressure from both levers slowly.

4. Move To Choke Position.

Next is the choke setting of the machine. Move the choke position to “FULL” if the engine is cold and move it to “Half-Choke” if the engine is warm.

After which, depress the fuel bulb. Continue doing this until the bulb is filled with fuel.

5. Put The Trimmer On A Flat Surface.

Now, lay the weed eater to the ground. This is an important step on how to start a Stihl weed eater.

Make sure the trimmer is laying on the ground and the opposite side of the starter grip handle is the one in contact with the surface. Also make sure the trimmer line is not touching any object or the ground.

6. Pull The Starter Trigger Slowly Until There Is Resistance.

Finally, slowly pull the starter grip handle. You should feel resistance and then proceed to give a sharp tug after.

Now, the rope should be guided back to the rope storage to prevent it from tangling. Give another four more strong and fast pulls before you move the choke lever to the middle setting. Continue doing so until the machine’s engine successfully starts.

Lastly, move the throttle trigger to its idle setting after starting the engine.

How to Start a Stihl Gas Powered Hedge Trimmer

Stihl manufactures hedge trimmers in compact models and pole models with blades mounted on long shafts. Pole models contain transmission systems which connect the cutting blades to the hand-held motor. Both types start in the same way with only slight differences in controls. Details do change slightly from model to model, so consult the owner's manual for information specific to your machine.

Mix 2 1/2 fluid ounces of two-cycle engine oil with one gallon of 89 octane unleaded gasoline. Use only fresh gasoline. Stihl recommends Stihl two-cycle oil but equivalent brands work. Fill the hedge trimmer fuel tank and replace the cap. Tighten the cap snugly. Finger tight is good enough.

  • Stihl manufactures hedge trimmers in compact models and pole models with blades mounted on long shafts.
  • Stihl recommends Stihl two-cycle oil but equivalent brands work.

Remove the plastic sheath from the trimmer blade and set the machine on the ground. When starting the machine keep the engine upright. Do not place a foot on the shaft of a pole trimmer.

Raise the blade lock lever to the lock position. Find this lever at the rear of compact trimmer throttle handles. Pole trimmers do not have the same feature--blade movement depends on engine speed.

Set the throttle of Stihl compact trimmers by squeezing the throttle trigger closed and sliding the throttle lock switch forward. Find this switch on the top of the handle forward of the trigger. Release the throttle trigger and the slide should hold it fully open. Squeeze the throttle trigger of Stihl pole trimmers and slide the throttle lock on the top of the grip back to Start. Release the trigger and it holds the setting.

  • Remove the plastic sheath from the trimmer blade and set the machine on the ground.
  • Find this switch on the top of the handle forward of the trigger.

Find the choke lever on the top left of the motor above the carburetor housing. Controls vary--the choke may be a lever or a knob and pointer. Set the choke to the closed position. Stihl marks the closed settings with a vertical line with horizontal lines above and below.

Find the primer bulb, which is a rubber bulb located near the choke on the top of the carburetor. Press the primer bulb no fewer than five times. Resistance increases when fuel begins flowing. Pumping too much gas through the system floods the carburetor. Stop priming after five pumps and try starting the trimmer.

  • Find the choke lever on the top left of the motor above the carburetor housing.
  • Find the primer bulb, which is a rubber bulb located near the choke on the top of the carburetor.

Hold the trimmer down with the left hand and grasp the handle of the starter cord with the right. Pull slowly until you feel resistance, then pull with short fast strokes. Do not use the full length of the starter rope. Repeat until the engine fires, usually no more than five good pulls.

Move the choke control to full open position as soon as the engine fires. Stihl marks fully open with a symbol like three parallel lines.

Depress the throttle trigger on compact trimmers as soon as the engine runs. This releases the throttle lock and reduces engine speed to an idle. Squeezing and releasing the throttle trigger on pole trimmers allows the trigger lock to shift to the Run position automatically.

  • Hold the trimmer down with the left hand and grasp the handle of the starter cord with the right.
  • Move the choke control to full open position as soon as the engine fires.

Starting Stihl trimmers after a brief shutdown should not require more than setting the throttle trigger to Run, making certain the choke is open and pulling the starter rope until the engine fires. Stihl recommends removing the spark plug to allow a flooded carburetor to vent fuel. A simpler solution involves opening the choke, setting the machine down and coming back in half an hour.

Thereof, how do you choke a Stihl chainsaw?

The choke position is the fourth setting on the master control lever. This setting is used to start the saw when its motor is cold. Stihl chainsaws denote the choke position using a nearly horizontal squiggle between two vertical lines at the lowest position on the master control lever.

Also, how do you Unflood a Stihl chainsaw? How to Troubleshoot a Stihl Chainsaw With a Flooding Engine

  1. Move the" Master" control switch to the cold start position.
  2. Pull the spark plug wire off of the spark plug and remove the spark plug from the cylinder head.
  3. Pull on the engine starter multiple times to clear the fuel out of the cylinder.

Also Know, why does my Stihl chainsaw not start?

Dirty or clogged fuel tanks, dirty fuel filters and lines, loose fuel hoses, dirty air filters and a dirty carburetor can all restrict fuel flow. Check, clean and replace all the fuel system parts before moving into the internal engine, as gas problems create a majority of starting problems.

Do you start a chainsaw with the brake on?

Always start your chainsaw with the chain brake engaged so the chain does not move.

What Is the Choke Position on a STIHL Chainsaw?

By Daniel Thompson

The choke position gets your chainsaw running from a cold start.

Stihl chainsaw ignition systems use a four-position lever called the master control lever. The choke position is the fourth setting on the master control lever. This setting is used to start the saw when its motor is cold. Stihl chainsaws denote the choke position using a nearly horizontal squiggle between two vertical lines at the lowest position on the master control lever. The choke position on Stihl chainsaws is often referred to as the cold start position.

How It Works

When your chainsaw's engine is cold, the droplets of gasoline entering the main cylinder do not evaporate properly. This impairs the ability of the saw to generate enough compression to start the motor. The choke position increases the richness of the air and fuel mixture the carburetor sprays into the cylinder. With the master control lever in the choke position, the flow of fuel into the engine increases and the flow of air decreases.

Using the Choke Position

Set the chain brake on your saw and put the master control lever into the choke position. Pull the starter cord until the engine begins to turn over. Quickly switch the master control lever to the warm-start position and pull the starter cord until the engine starts to run. Once the engine is running, rev the throttle briefly to ensure the motor continues running. Operating the throttle automatically sets the master control lever into the run position. Always start your saw on the ground with the blade free of obstructions and away from bystanders.

Flooded Engines

The choke position can flood the engine with too much fuel, preventing it from starting. This problem commonly occurs when you fail to switch the master control lever to warm start quickly enough. Over time the excess fuel will evaporate and allow your chainsaw to start normally. Once the engine has been operating long enough for the motor to get hot, you can start the engine using the warm-start setting on the master control lever. Using the choke position to start a warm saw often causes it to flood. In most cases it only takes about a minute for the engine to warm up.

Safety Considerations

Revving the throttle on your saw while the chain brake is engaged for more than a few seconds can seriously damage your saw. When you are using the starter cord, pull it out several inches from the engine housing until you feel strong tension on the cord. Next pull the starter cord out the rest of the way in one smooth motion. Releasing a fully extended starter cord and allowing it to fly back into the engine can damage the winding mechanism.
