So recently, I took in my 86 SC for an emissions test, and it failed. The guy running the test said it was running rich, and I had been smelling fuel intermittently before.

2500 rpm Standard Test
CO% 1.20 6.06 Fail
HC (PPM) 220 206 Pass
Dilution CO+CO2% 6.00 16.57

Idle test Standard Test
CO% 1.20 0.77 Pass
HC (PPM) 220 144 Pass
Dilution CO+CO2% 6.00 14.37

Any suggestions? I'm new to fuel injection, and I'd rather get it right the first time.
