Thanks for the bump, Oz.

And thanks for the explanation, B5. That makes more sense. I did get a gauge with the kit, so I'll measure it tomorrow.

As for the step-up piston adjustment, how far did you turn yours in? My car is running a bit rich, so I backed that screw out about one-half turn. But I'm not sure how much effect (if any) such a small adjustment will have. I'll probably just play with it until I get it right.
