I ran autolite 3932 spark plugs last year but they were always wet looking so I changed to NGK 5672-8 (#7173) now they are white to grey lean my question is should I stay with the ngk and adjust jetting to them or go back to autolites also what do you recomend my valve setting or lash to be on a solid roller settup with aluminum heads no thermostat motor stays about 170 degrees specs below. thanks for any info in advance I just run the lakes not profesional racer by any means.
