[Healeys] Emissions Compliance in New Jersey

[Oudesluys]

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.
