I used to ride a 2 stroke motorbike to school. It emitted more CO and NOx than an SUV. Upon saying that, SUVs still (obviously) emit more CO2 than 2 banger bikes. And the biggest polluter is still cargo ships with their massive 2 stroke engines burning high-sulfur, heavy fuel oil. I'm not sure about the USA, but at least in Australia 2 strokes aren't very common at all these days. I don't remember the last time I saw a 2 stroke lawnmower or any other type of garden tool. Electric is probably more popular than petrol for home use, as it doesn't require you to keep a little tank of petrol lying around and it's a lot quieter.
