Question about emissions
I've changed the initial timing setting so the engine gets 36* total centrifigal advance. This move put the idle timing somewhere around 12-16*BTDC. Now when I try and pass emissions the hydrocarbons fails miserably and was wondering what would happen if I went back to the curb idle 4*BTDC factory setting? Or could it be something else? I removed the air cleaner and PCV valve before going the second time and hydrocarbons went down some but not enough. Any suggestions?

Certain vehicles are exempt from inspections, but they do vary, so be sure to check what is required for yours.
I doubt that timing affects your emissions.
I am wondering why you are even getting an emissions check if your vette is a 79 like your name implies.
Your car is over 25 years old and exempt. Get a collector, or historic registration.
The following vehicles are exempt from inspection requirements (N.J.A.C. 13:20-7.2):
Historic motor vehicles
Collector motor vehicles
Approved Collector Vehicles which are less than 25 years old
