Cable could be sticking or the carb could be dirty causing it to stick.

Welcome to the forum!

First make sure the slide isnt stuck wide open then if its not definitely pull the carb and clean it again could have picked up some more dirt from the tank. Thats where I would start.

Are you almost out of gas? Mine does that when I'm running low.

I had a similar problem with mine and it was fixed by a simple and quick carb cleaning.

Most likely a stuck slide as mentioned above. Pull the carb and clean it while you've got it off, its a 30 minute job.

If it's not the slide, you might have an air leak.
