I have an 86 Samurai that I am trying to get smogged and am having a difficult time. The Samurai idles rough at first and then stays at between 1650 and 1800 RPM's and the choke plate does not open all the way. We (smog tech) have adjusted the idle screw, does not lower RPM. The tech said it was the "wax element." Well, before I start messing with stuff I do not know about, I thought I'd check and see if anyone had some advice on how to lower the RPM's. I see the "wax element" referenced in the manual, but cannot even find one to get a price.
