emission and timing 200 1985

I thought I read a message where someone recommended to retard (really retard) below the normal 12 deg the mechanical timing in order to lower emissions. Am I correct or did I just dreamed this? My issue is that the car fails smog test with high HC (1.98 gr/mile when the max is 0.8) and just above limit on NOx (2.3 gr/mile , max is 2). For ref. the CO is 7 gr/mile with a limit at 15.

I am planning on trying the idea (from Lucid) of plugging off the vaccum input to the ICU but was going to modify the timing to 10 deg as well.

Thanks for your input
