Pro Chain Saw 46cc 20″

Experienced gardeners share their insights in answering this question :
Most starting problems with chainsaws are caused by flooding. Read and follow the start up procedure in your manual. Probably similar to this:
Start Procedure
Cold:

Ignition on/off to on
Set compression release – optional step even if saw is equipped with a compression release
Pull (close) choke, set fast idle (done when choke closed on some saws); pull starter and listen for an attempt to start. once heard (usually two pulls)
Set compression release – optional step even if saw is equipped with a compression release
Push (open) choke pull starter until it starts. (usually first pull)
Warm:

Ignition on/off to on
Set compression release – optional step even if saw is equipped with a compression release
Pull (close) choke, set fast idle (done when choke closed on some saws) – Don’t pull with choke closed.
Push (open) choke, pull starter until it starts. (usually first pull)
All new saws regardless of maker are set to run extremely lean to meet EPA mandated air quality standards. They are also fitted with a device to restrict richening the carburetor beyond initial factory settings this too required by the EPA. Most big box stores put them on the shelf and sell them to the consumer with no thought of how elevation may impact saw performance or longevity. Homeowners usually aren’t concerned about changes in the saws performance until it quits operating. This combination results in many destroyed saws and homeowner saws of most brands being called trash!
I don’t know what the elevation where you are located is but I’ll wager it is different than where the saw was set up. If my saw I’d visit a good (Stihl in my case) saw shop, and pay a couple of $ to have the carb adjusted (fresh fuel mix (1.5 months or less) 40:1 (3.2oz/1gal Husqvarna or Stihl 2 cycle oil) oil/fuel ratio, and the clean air filter). Any money spent is worth less than the aggravation when the saw won’t start and you might spark a mutually beneficial relationship with a local merchant. HTH

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 :

The carburetor might be clogged. A clogged carburetor is often caused by leaving fuel in the chainsaw for a long period of time. Over time, some of the ingredients in the fuel will evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and prevent the engine from starting.
There may be old or bad fuel in the carburetor float bowl. Over time, some of the ingredients in the fuel may evaporate, leaving behind a thicker, stickier substance. This sticky fuel can clog up the carburetor and make the engine hard to start. If the carburetor is clogged, try cleaning it with carburetor cleaner.
There could be various causes: incorrect fuel mixture, carburation not calibrated properly, or a wet spark plug. In spite of their power and robustness, chainsaws are actually rather delicate machines that require careful and precise maintenance at every stage of their life cycle.

If a mower is hard to start, it may be the result of a dirty carburetor and/or a clogged air filter. Use a screwdriver to remove the carburetor and clean any dirt out of it with a rag. Clean the air filter or replace it if it`s disposable.
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.
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.
