AG burr finish

My trusty old 499" cuda with Dominator carb will leave a bit of smell on my clothes after I drive it. It did that with an 800DP as well, and basically every carbureted vehicle I've been in will do that. I think it's fair to say that's the result of unburned fuel....but I also think it's a low RPM, sitting in traffic issue. I don't think it would happen if I were only in the car at higher RPM.

I don't recall when/where but not too long ago I was looking at a video of a guy's engine.... he put a high quality camera into the intake and filmed it as he drive around town. I wish I could remember...but in any case it was a modern car that was Japanese. I think a Toyota inline 6 in a Supra.

When he would idle, you'd see some fuel swirling around. Not a lot of actual separation, but you could see the fuel in the air and that proved it wasn't well mixed. But as soon as he would hit the gas, it would pretty much vanish and while you could see turbulence from the camera shaking, you couldn't see any sort of fuel on the walls or in the air. It was actually kinda boring to watch.

I guess the point is...the Toyota 6 is probably far more 'friendly' than a nasty Kaase race engine. I don't think the kind of fuel puddling we see in the Kaase video happens on all engines all the time.
