Hi Just replaced the wax stat in my single carb 998 wasnt sure it they made different ones mine had a black band and the new one has a blue band installed back on the car ran it now runs rough won't sit and idle without turning idle screw up. took it for a ride seemed like it might be running lean so brought it home took out the plugs and they looked on the whitish side. Not sure if I should richen the mixture or could it be the wrong part its the one with the aluminum housing not the plastic ones thanks for your help.
