I agree with Kees
3.5% Co or less can easily be met by HD 8s in proper tune, and of course
everything else needs to be ok as well. No need for special tricks.

Dmne: Re: [Healeys] Emissions Compliance in New Jersey
10% CO at idle seems extremely high to me. There must be something out of
tune or worn here. Between 2-5% CO should be fairly easily attained using a
Colortune with properly build and maintained SU's . In the 50's and 60's
5-10% CO was not regarded as excessive.
High CO values always coincide with high hydro-carbon emissions because of
partially unburned fuel. Another source of hydro-carbons is excessive oil
consumption because of worn piston(ring)s Servicing the carbs and tuning
them properly will result in meeting the standards.
