Honda BF20 acceleration problem

[Sarrre]

Hey guys!

Got a problem (again) with a Honda BF20 from 2015. About one year ago I got problem with cold starting, and replaced the auto choke to solve the problem. At the same time I cleaned the carb in an ultrasonic cleaner just to make sure it wouldn't be the problem.
Now I have another problem with acceleration. As you can see in the video below, it starts easily but stalls when twisting the throttle.
Is it really possible that the carb is dirty again? What can else be the problem? Are there some easy troubleshooting for this?

Accelerator pump is not working, You would benefit greatly from a manual. Often the passage between the pump chamber and the spray nozzle gets blocked and can often be cleaned by repeatedly spraying throttle body cleaner, soaking and then compressed air. Sometimes its just easier to buy a new carb
