A lawn-mower pollutes like ten cars!

I read on the US Environment Protection Agency website, that using a petrol lawn mower produces more carbon dioxide in an hour than a car produces whilst covering 300 miles. I had assumed that, when burning petrol, all of the carbon combines with oxygen in the air so the co2 produced varies in proportion to the amount of fuel burnt? What have I missed?

Many of these engines run on a fuel oil mixture which is more polluting.

None of them have a catalytic converter, so unburnt fuel comes out the exhaust.

Most of them run rich or the exhaust valves would be burnt.
