Hi, I have a '73 Dodge Challenger with a 318, automatic. Mileage is 127,232mi.
We took it Friday to have it tested, and it passed everything except the HC on the idle. Initial readings were:Loaded HC 00225/standard400
Loaded CO 3.58/standard3.75, Idle CO 3.02/standard5.00, Idle HC 00738/standard400
They retarded the timing to zero, and the readings changed to Loaded HC 192, Loaded CO 3.54, Idle CO0.80,Idle HC 2436, which is triple what it was to begin with! What do you suggest? Everything else looks pretty good, I think. Thanks for any info. I need this to pass as it is my daily driver, and I can't qualify for a waiver, as it hasn't been registered in this state for a year yet.
