Why did my weedeater keep going after I turned the power off?

[bluemoonKY]

I used to be a groundskeeper, and I operated a weedeater for the job. I had a gas-powered weedeater. I don't remember the make or model of the weedeater. When I turned power button to off to turn off the weedeater, the engine on my weedeater would sometimes keep on going for over a minute after I turned the weedeater off. Why did my weedeater engine keep on running after I turned the power to off?

Perhaps the on/off switch is just a fuel flow shutoff.

It's obviously possessed. What more evidence do you need?

Dieseling is so-named because it is similar in appearance to how diesel engines operate: by firing without a spark.
