Took my rig (85 FJ60) into get inspected and emissions tested last week and it failed the emissions test (living in Pennsylvania)...pretty misearably I might add.
The HydroCarbon Parts Per Million (HC ppm)...as i was told is unburnt fuel.... came back at 1192 while the limit is 220. Now, this is only at idle. When tested at 2500 RPM it comes back at 109 while the limit is still 220. So I am thinking it is running rich at idle, or the choke is slightly stuck.
Could someone clue me on how I go about adjusting the air/fuel mixture on the Carb. Also, is there a way to tell if the choke is stuck. I feel that my choke is functioning properly since it helps in starting and my idle decreases once i take the choke off.
Thanks for your help,
