The fact that the the engine won't accelerate is most likely a carburetor problem. Being that is was out of use for 2 years, it quite possibly has gum/varnish built up in the fuel system. The sensitive internal parts of the carburetor are most liklely dried out and brittle. They need to be flexible and soft. At the minimum, you need to have a gasket and diaghragm kit installed in it or even a complete rebuild kit.
The only other thing to try is to try to adjust the L and H mixture screws on the carburetor. Many times this will cure a non-acceleration issue, the only problem being what I think you have stated. It is difficult to grasp these screws as they have been made this way on purpose to prevent tampering with the fuel mixture (per EPA emmission rules).
Small aluminum tubing (sold at hardware and home improvement stores) forced over the heads of the screws will turn them and so will the crimping end of a #22 wire connector (ring terminal or spade connector works).Regular needlenosed pliars can't reach them...even the smaller jeweler's kind. Special tools have been made to adjust these carbs and once you know their shape, sometimes you can purchase one on Ebay.

What are the adjustments for the high and low mixture screws on the carbureator? the carbureator is from an echo 500vl chainsaw.


Echo thinks your actual model number is CS-550EVL. Page 14 lists the starting points for carburetor adjustment here:
http://www.echo-usa.com/pdf/documentation/CS550evle_010186.pdf
Additional manuals for you saw can be found here:
EchoUSA
http://www.echo-usa.com/documentation.asp
More choices can be found by typing CS in the model: window then clicking “Search”.

Once initialized this is the best procedure I have found.
Carburetor Adjustment by Madsens.com
http://www.madsens1.com/saw%20carb%20tune.htm
CW is leaner; to lean will destroy the saw. If over tightened closed (CW) the adjustment screw faces are easily marred; marred adjustments are difficult to impossible to set properly.
Clean the air filter; adjusting with a dirty filter can cause a run lean condition once cleaned and the saw run.

There are 2 wav (sound - idle & full – may not be highlighted) files that I find most helpful, I think you will too. HTH

Craftsman lawn mower can not run without pumping the red button


Hello,

The fact you need to keep pushing the RED or "Primer" button says that your engine is running too lean ie. not getting enough gas.

You probably have a carburator problem due to the old gas gumming up the inside of the carb. The gum and dirt is clogging some of the internal passages of the carburator. It will need to removed from the engine and cleaned. The carburator is held to the engine by 2 bolts and is simple inside. Carefully clean the carb. with either carb. cleaner or laquer thinner or similar good solvant. Reinstall and you should be fine.

Also be sure to check your air filter and replace if dirty.
The red button is a "primer" that pumps extra gas into the engine. It is normally used only only for statrup so if need to use it while the engine's running, you're running too lean.
