What to do if you’ve run out of STIHL chain saw oil?

STIHL ms 180 starts with a splash of gasoline in the cylinder

The chain saw til MS 180 does not start. Washed the spark plug with acetone, sanded down with a fine sandpaper. For weeks and months. I didn’t use it, gas and oil were in the tank, but it would start in 50th time before. Please tell me where to look and what to do. And please send me the repair manual if you have it available.

Т.к. you had gas in the tank, 80 percent you have to clean the carburettor first. Second, the saw will start if there is fuel in the cylinder, spark and compression. Lack of fuel supply can be seen by a dry spark plug (disassemble and clean the carburetor, change the fuel filter, clean the pulse channel).If there is no spark then change the spark plug, if the change does not help, you must change the magneto. If there is no compression, you need to change the piston, cylinder and packings. My advice would be to first remove the muffler and check the condition of the piston (is there any scuffing on the piston or not).

You can not leave old gas in the tank of the saw is 100%. Diluted gasoline loses its properties pretty fast. There are many sawmills in our area and we are getting more and more experience.

There was a case: in one shop, in a short time all saws broke down at once the cause of searching for a short time, it turned out that gasoline diluted with oil in a large tank from which then filled the saw for weeks and months. All pistons have died out. Naturally the oil loses its properties in diluted form, it is advisable to do it only once, every day dilute a new portion. If left to drain from the tank before storage.

Advice on how to find out the compression in a chainsaw: the easiest way, lift it by the starter rope. It should go down slowly, characteristically squelching compression.

Another tip: You should only turn off your chainsaw when it is idling because when you turn the flag on the stop position the coil gets shorted to the common ground and the spark goes out. Sometimes, the ignition is turned off without reducing the RPM and the short circuit to the ground lasts a very long time, not every coil can withstand it.

Why am I writing all this? Even though the information doesn’t answer the question directly, these facts will help you to find the cause of your problem, maybe you will see what you were doing wrong and already know where to look. (I have, for example, on 270.On a Stihl, ignition coil burned out, shut it off at high rpm in a hurry.)

How to check the spark: unscrewed plug put on a piece of iron saw and twist the starter, indoors, the spark is clearly visible. If not, another way to be sure, instead of a spark plug, insert your finger into the cap and twist the crankshaft (will not kill for sure, but will be an unpleasant feeling but will know for sure if there is spark or not)

In your case, I would change the gasoline to a new diluted, and on the suction pump, cold start spinning until the candle is wet. Then I dried it off, refitted it, and started it up again as usual. If ignition, filters and compression are normal, it won’t go anywhere.

Risks of low-quality fuel

In the composition of different low-octane gasoline and fuel surrogates contain alcohol components, which require more time for complete combustion. The economical use of such fuel is questionable, as there are a number of factors, confirming the inefficient operation and forced wear and tear of the engine.

Plug greasing is promoted by the use of heat-resistant engine oils for 4-stroke engines, heavy wear of compression rings or the entire piston group in general.

What to do if the spark plug gets greasy on the chainsaw

If there is a suspicion of a primed spark plug, it is necessary to examine it. Using a spark plug wrench, it is unscrewed and carefully studied. If the plug is wet, but there is a spark, then it is sure to have been primed.

Proper preparation of the fuel mixture also affects the life of the plug and can also put it out of operation, about what proportions to mix gasoline and oil, read here.

Many experienced owners are able to identify the current condition of the spark plug with a high degree of certainty by its color. This is a procedure that should be repeated at regular intervals.

  • Light brown fouling is exactly what all owners want to see. In this case, the functionality of the chainsaw is not impaired.
  • Black soot signals an unbalanced mixture, namely a lack of oxygen in the fuel chamber. If the situation is not corrected, there is a high risk that the chainsaw will overfill the spark plug.
  • If you find corrosion on the plug or too much distance between the electrodes, it is likely that a lean fuel mixture is used.

  • If the repair takes place in the field conditions, the saw is installed on a level surface (in a workshop everything is easier. use the table to help), then the BB wire is pulled out from the spark plug, the spark plug electrodes are wiped dry with a wrench. The circuit breaker system must be on.
  • Unscrew the lid of the air filter, which is cleaned of dirt.
  • After that, the control lever is set at the minimum throttle position and the starter cord is jerked up to 10 times, but not less than 5. The combustion chamber is thereby cleaned of excessive fuel.
  • Having returned back the air filter, installed the spark plug and connected the wire, you should pull the starter cord a few more times. The throttle valve must remain open.

If these actions are performed correctly, the saw will come back to life.
