Hydrocarbons. The last test, yesterday, I missed by 4 ppm at 15mph. The
limit is 55 ppm, and I came in at 59 ppm. Everything else passed. CO %
and NO ppm are great.
When you say great - are they better than maker's spec? High HC low CO
suggest a weak mixture, so possibly an air leak in the induction system
or engine breathers?
