12 months ago I passed the
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?
