Why does my chainsaw bog down when I give it gas?

Why does my chainsaw dies when I give it gas?
Because your chainsaw will idle, but dies when it is revved up to full power, it means that the filter is only partially clogged; it will allow enough fuel to the engine to run on idle, but not enough to sustain full throttle. If the filter becomes clogged, not enough fuel will reach the engine for it to run properly.
Why does my Stihl chainsaw bog down?
Without the right amount of air and fuel in the piston cylinder, the 2-cycle engine in a Stihl chain saw runs inefficiently and the saw loses power. When the saw bogs down during cutting, it’s usually the high-speed screw you need to adjust.

Low Speed Fuel Adjustment – This is the adjustment that controls the proportion of fuel in the air/fuel mixture at idle speed.
Why does my 2 stroke die when I give it gas?
Carburetor. Carburetors mix air and fuel at a precise ratio for the combustion process. Anything that prevents the proper airflow or entry of fuel will result in the inefficiency of the carburetor. This can lead to the symptom of your two-stroke engine dying at full throttle.
Why does my chainsaw bog down under load?
Many chainsaw operators first notice a problem with chainsaws bogging down when they’re using the chainsaw under load, and this is usually the result of poor air circulation. This issue is caused by a clogged air filter on the chainsaw. Remove the air filter from the chainsaw.

So if you have a clogged filter, the fuel is too rich and not getting enough air. Or you could have too much oil in the fuel as a two stroke mix. There may not be enough actual gasoline-burning and eventually that fouls the plug and it just cannot sustain running. So check your fuel ratio to make sure it’s correct.

The car will stall if the valve is too clogged or when it finally fails. If, while holding the accelerator pedal down, a small amount of pressure keeps the car running at a stop, the idle control valve may require attention.
