Chain saw ran fine one day, would not start the next. I replaced gasoline with fresh, replaced the spark plug, verified that there is spark. But no start, even with ether.
Experienced gardeners share their insights in answering this question :
I would suggest the piston has scuffed, remove the muffler and look at the exhaust face of the piston through the open exhaust port, any signs of scuffing or damage and you will need to remove the cylinder to assess the amount of damge.

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

If a petrol engine chainsaw won`t start, it is usually due to an engine malfunction, specifically relating to the fuel system (which mixes the fuel with air and feeds this mixture into the engine`s combustion chamber) or ignition system (which produces the spark that starts combustion and thereby causes the engine to …
Just let the saw sit for 30 min and the excess gas will evaporate. Remove the spark plug, dry it, crank over the engine a few times to dry the cylinder. Now refit the plug and try again. Set the switch to “On”, set throttle to fully open, set choke to “Off” and crank over the engine.
If your STIHL chainsaw is going to have a problem, it`s likely to be with a worn carburetor, bad spark plugs, loose fuel hoses, or clogged fuel lines. You should also inspect the fuel intake system and ensure that there are no compression issues.
One tell-tale sign that a chainsaw has flooded is the smell of fresh petrol near the muffler. To ascertain whether this is indeed the problem, simply disassemble the part, pull the starter cord as if you were switching on the engine, then dry it, reassemble it and try switching it on again.
With the choke in the “off” position, pull the engine`s crank cord through again. The engine should start in 1 to 3 pulls. Try it first without using the throttle control—unless recommended by the manufacturer.
A dirty carburetor, bad gasoline and low-quality two-stroke oil that creates deposits all contribute to chainsaw starting problems.
Many people wonder if a flooded chainsaw will fix itself? The answer is yes, but not always. By letting the chainsaw sit for about 20 minutes it will allow some of the fuel inside the engine to evaporate.
If your chainsaw does not start, the fuel may be too hot. To prevent this from happening, always use fresh fuel and reduce your operating time when the weather is warm. If your chainsaw will not start, place it in a cool area away from sunlight for at least 20 minutes.
A chainsaw`s carburetor mixes air and fuel to start the internal combustion engine. If fuel has been left in the engine for too long, it can become sticky and clog the carburetor, preventing it from starting. If the clog is minor, clean out the carburetor.
A flooded engine is an internal combustion engine that has been fed an excessively rich air-fuel mixture that cannot be ignited. This is caused by the mixture exceeding the upper explosive limit for the particular fuel. An engine in this condition will not start until the excessively rich mixture has been cleared.
A chainsaw can run without the chain. But it should only be run in short bursts, a few minutes at a time. This will help stop the chainsaw from overheating, which can cause significant damage. Plus, it is vital to observe safety protocols and keep the bar away from people.
When engaged, the chain brake stops the chain from rotating around the saw`s guide bar. When using a chainsaw, you should always start it with the chain brake engaged so the chain does not move.
If your chainsaw still starts and then stops working, check the air filter. Clean or replace the air filter if it is dirty or damaged. Another reason that your chainsaw starts and then stops working could be that the spark arrestor is dirty or clogged. If this is the case, clean it with a wire brush.
If you run a chainsaw without bar oil, it`s likely that the chain will heat up and eventually break. This can cause extensive damage to the chainsaw and may even require a new chain and bar. It`s imperative that you use the correct amount of bar oil.
The carburetor on a chain saw is pretty simple, as carbs go, but it`s not entirely uncomplicated. The job of the carb is to accurately meter extremely tiny quantities of fuel and mix it with the air entering the engine so that the engine runs properly.

I was using the saw as a chain saw last weekend to cut up an old tree stump when the chain came off. I don’t know how to access it to put it back on and don’t have a user manual. The saw belonged to my late father and I don’t know if he even kept the manual.
ANSWER : You will have to remove the cover on the side the chain bar goes into. There should be one or two nuts holding the cover on the side. The is also a chain tension adjuster you may have to loosen to put it back on. Make note of the direction of the teeth on the chain. It is an directional chain. The tension adjuster is usually a flat head screw on the front side right beside the chain bar.Unless it is a really old saw, manuals are available from most manufacturers for free download. See if you can locate a brand name and model number.
