Kickdown adjustment?

I just intstalled a BM streey/strip shift improver in my 904. Why you adjust the kickdown linkage have someone under the car push the spring loaded throttle lever all the way forward and after you loosen the screw on the throttle rod push it down to remove the slack. with the throttle lever pushed forward the appropriate adjustment should have the back end of the adjuster sleeve on the carb end butted up against the stop on the throttle linkage. This method only works if you have the three piece kickdown linkage. for the one piece there is a different method...

cant remember it though.

I'm still not happy with the way mine shifts. lengthening and shortening the rod will adjust the shift points.
