HC levels on emissions test.... PASSED, good ole Metro Nashville Options

[malcolm2]

'75 1911 L-Jet with about 7000 miles on it, and a fresh oil change this week. Fresh injectors before the first test. Probably running 87 oct E10 gas today. Might have been 93 100% last year.

12 months ago I passed the state county sniff test here are the results from 10/2013:
HC 399 limit 500
CO 0.65 limit 5.0
CO2 11 no limit listed

and from just moments ago 10/2014:
HC 428 limit 500
CO 3.83 limit 5.0
CO2 11.53 no limit listed

2 different inspection stations, not sure if that matters.

The CO seems to have jumped. I did tweek a few teeth on the AFM between the tests. IIRC I have moved it 9 teeth.

Plus the HC is getting close to the limit. I can't remember the RPMs during either test, but they tend to be about 1000, a bit high.

It passed but I want to be pro-active, any thoughts about the CO jump and pulling the HC down for next year?

That's a bummer you have to get your car inspected. Right next door to you here, anything over 35 years old, pay insurance and registration, they hand you a plate, and off you go.

It is my own fault. 1975 is the last year to get inspections. If I had bought a 1974 I would not have to deal with it.

I should make a correction. It is not the STATE it is Davidson County. Years ago they decided to do this test, and included the 7 contiguous counties of which I live in one.

But you are correct, they should just make it 20 years of testing and then stop. I suppose some brilliant politician figured if they did that everyone would be driving 21 year old cars so the new car dealers would suffer.

The increased use of older cars might happen for a year or two, then it would be back to normal..... dumb asses! (IMG:style_emoticons/default/stirthepot.gif)
