As the title said, I believe I put regular gas into my echo tb580 leaf blower. It was an small old gas tank and I didn’t know the wiser…

Ran fine for 5 minutes or so until it just suddenly stopped. Started it up again after a few minutes and it stopped after a minute or so, no odd noises or anything. Engine was extremely hot.

Can I just empty the gas in the tank, mix 50:1 gas/oil and then pour that back in and start it up?

Any other suggestions? Thanks
