Failed emmissions
Was high on HC,read 12.0256 and the limit is 7.0.CO was 52.1595,Limit is 120.0.NOx was 4.9239,Limit is 7.0.Any suggestions.What's the main cause for high HC.This is all on a 70 1/2t 250 6cyl w/electronic ignition, .060 plug gap,timing at 10 atc.If the timing was to far advanced,would that be the cause?Was at 14,It did ping a little when accelerating. Checked after the test and set at 10.Thanks for any advise,Mike
