Given the extraordinary amount of pollution produced by small engines, you'd think that cat converters would be more common by now. I believe there's US legislation requiring serious reduction in pollution in new machines by 2007, but I'm not sure. My research did turn up lobbying efforts by Briggs and Straton to defeat such legislation in California a few years back - way to lead us forward, B&S!
Anyway I've found a couple of links for companies who claim to be working on aftermarket cat converters for small engines, but so far nothing actually shipping. Anyone know of a company who's doing this for real?
In a related question, a CBC TV news item a while back featured a guy in the maritimes who's been custom-building these things for just this purpose, and had them tested and proven effective by some Canuck gov department, but he can't seem to get anyone interested in funding manufacture. I'd love to have the guy's name.
