Honda rotovator, where does this tube go?

I took the air filter off to have a look and this sprung out of nowhere, I was suspicious but couldn't find anywhere for it to go. I ran the engine for a minute and it stopped, now it won't start. Can someone please help in detail! Honda rotovator, where does this tube go - 1

I don't think it is the fuel line. I reckon it is the overflow from the carby. That black hose along the bottom is the fuel line
These machines do hard work and that fiddly little line would not keep up. I bet if you turned it down towards the camera, it would lay neatly along the red chassis.

If the hose was attached to anything, you would have felt some resistance when you pulled the air filter off.

Don't know that machine but it looks like a fuel line.

Probably goes to whatever is supposed to be on the two studs and gasket under and left of your thumb. Maybe part of carburetor.
