100% agreed on that. The AIR program dude who did my truck explained that the brown cloud was mostly particulates, which isn't measured by the mobile vans anyway. Some of them are kicked up by vehicular traffic (yeah - how do you curb THAT?), and some of them (small fraction) are diesel soot. But the greatest fraction is not caused by humans, and has been there for millions of years whenever there's an inversion, but is caused by particulates which had been kicked up by previous winds getting caught in the inversion, trapped in the Platte River Valley. Just as we violate the EPA ozone levels every summer, most ozone is caused by our naturally occurring high altitude sunlight (UV) even if there were no anthropogenic NxOx or VOCs to enhance it's formation, and the brown cloud was there long before Henry Ford ever had a vehicular gleam in his eye.

Driven east on 76 lately past all the gas wells? The air is so rotten that it's hard not to gag as you drive through with your windows up, and the color of the "air" turns a nice shade of brownish green...

Sorry that Timms 2F desmog thread has been hijacked.

Hopefully this will be a moot point for me if the 55 parts truck I am getting has a good 2f. Then this thread can continue with whoever buys my FJ60 2f!

JeFff> Some of them are kicked up by vehicular traffic (yeah - how do you curb THAT?)

The city of Colo Springs has a mandate to begin sweeping up the sand they put on the road within 24 hours of applying it, in order to combat the brown cloud. I personally think it's a waste of time on surface streets. And this 'dust control' nonsense has led them to increase the salt content of the road mix from 5% to 20%. Just what we needed: more 'fender solvent'.

Well, I'm running a de-smogged 2F, carb rebuilt by Jim C. and an electronic distributor in my project 40. I haven't tooled around in the 40 yet, but I don't anticipate any performance problems. It did pass emissions (for a '69).
