If your Makita demo saw has an auto decompression feature but is not decompressing when attempting to start, there could be a few potential causes for this issue. Here are a few things you can check:

1. Check that the decompression valve is functioning properly. It could be clogged or stuck and not allow the engine to decompress.
2. Check the air filter. A dirty air filter can restrict airflow to the engine, making it difficult for the saw to start. Clean or replace the air filter as needed.
3. Check the spark plug. A fouled or worn spark plug can also make it difficult for the saw to start. Clean or replace the spark plug as needed.
4. Check the fuel filter. A clogged fuel filter can restrict fuel flow to the engine, making it difficult for the saw to start. Clean or replace the fuel filter as needed.
5. Check the carburetor. A dirty or clogged carburetor can restrict airflow and fuel flow to the engine, making it difficult for the saw to start. Clean or rebuild the carburetor as needed.
6. Check the fuel level. If the saw runs out of fuel, it will not start. Make sure the fuel tank is filled with fresh fuel.

It's worth mentioning that if the saw is still under warranty, it is best to contact Makita's customer service and ask for assistance. If you are not comfortable working with the engine, it is best to consult a professional or refer to the service manual for your specific saw.

Taking the carb completely off is not the same as just shooting gas into the manifold opening. Way to much air will keep the motor from firing. Before just reinstalling the carb remove the float bowl and check the pilot jet to make sure it is clear and not clogged. Most likely it will have a clogged pilot jet. If you just put the carb back on without checking to see if the jet isn't clear, you can try squirting gas into the back of the carb to see if it fires up. It should at least fire up for a quick second and then die out. If that happens it is a dirty clogged pilot jet. Reaffirming you will need to service your carb.

Here is the manual for it. https://www.makita.ca/data/upload/owners_manuals/DPC7311-HD%20&%20DPC7321HD-%20ENG_owner_English.pdf?tm=1645358236 Skipping at high revs could be both. I presume you put a new spark plug in and checked the gap? ..
