This makes me think of A Snow Mobile for George [1]. I'm not sure what the lead pollution impact of 2 stroke engines are (probably awful if you were able to find/use leaded gas) but in terms of low-hanging fruit its a perfect example of how regulation or deregulation can have a large effect on pollution. Growing up using 2 stroke weedeaters and chainsaws I had no idea how polluting they are. Granted we were using terribly small amounts of gas compared to snowmobiles but it still made me think of the health dangers of the exhaust. I have some nostalgic feelings towards the smell of 2 stroke exhaust (diesel exhaust as well) but after seeing the documentary I wouldn't buy another 2 stroke anything. http://www.imdb.com/title/tt1314278/ http://www.imdb.com/title/tt1314278/

"Growing up using 2 stroke weedeaters and chainsaws I had no idea how polluting they are." Terribly polluting. However, my understanding is that there is no potential for "fixing" chainsaws since a 4 stroke engine cannot run upside down - which is a requirement for a chainsaw. Am I mistaken ? Luckily we're starting to see a lot of battery operated chainsaws come onto the market with higher density Li-ion batteries. We're demoing a dewalt[1] chainsaw at my fire department and I have been using a Bosch reciprocating saw with a brush blade for light tree work for two years now ... but this is all light duty stuff and cannot replace large chainsaws...

  2-stroke engines are lubricated by their own fuel mix. There's no reason you can't mix oil and gas in a 4-cycle fuel mix. This is what the Stihl 4-cycle chainsaw does. Honda also makes small 4-stroke engines that work in any position, because Japan is awesome.
