I was mowing the back yard the other day and the mower just stopped (out of gas). Filled it up but it wouldn't start again. Tried to start it again today and no go. I got some energetic kids to come yank it endlessly but it just won't start. They said it's not the spark plug and it all looks fine except for one thing -- there is white smoke shooting out of the holes in the cover of this silver thing on the side (they think that's the muffler?), and after a while gas sprays out of the same place. Any ideas?
Thanks
