[tech] Smog check & timing
Hi all:
Assuming all else being constant, what is the relationship between ignition
timing and emissions? In other words, if the timing is advanced or
retarded, how does it affect hydrocarbons, NOx, and CO levels? This is in
relation to my 81's (1.7L EN, CIS) looming California smog test date.
Thanks for any insights, benton-----
