I just ran my 1971 Bronco with a 302 through the emissions test and failed. I have a Holley 670 TA carb and a RPM performer intake. I am running at 12 degs of timing. I do not know much about Holley's and don't really know a good mechanic out here in East Mesa nor do I want to pay someone to work on my rig. I was hoping you guys could help me out. Here is what it ran on the test:
HC loaded 288 with a standard of 450 (pass) HC idle 697 with a standard of 450 (fail)
CO loaded 7.47 with standard of 3.75 (fail) CO idle 10.37 with a standard of 5.0 (fail)
I looks like I am running rich to me. I just want to squeak it through as I've just come across a 90 5.0 mustang that I am going to swap in this summer. Any words of wisdom on this one. What sucks is that I live about 1/4 mile from Pinal county which would exempt me from emissions. Thanks for your help in advance. Dave
