Re: Failed emissions!!!

I'm guessing you are not leaning the mixture like you believe. Look 
at the workshop manual D:04:01. Clockwise increases CO, anti-
clockwise reduces CO. You should really check the CO by going 
through the full process. Also, the idle screw positions can affect 
the readings. Is the test you are going through at idle or under 
load.
