·I'm oh-for-2 on passing emissions. The first time I went in 'raw' (unprepared, just hoping) and my CO was 4.02 and my HC was 281 (passing is 1.80/200 at 15 MPH). I knew I was running rich, so I adjusted the carb much MUCH leaner (maybe to a fault) and replaced my spark plugs. I'm now 3.04/219. This is better, but I'm not really all that close.
Any advice? I think my EGR is suspect... It does not hold any vacuume if I hook up my hand-vacuume-pump.
Thanks guys,
