I have a 1986.5 HB with over 300,000 miles on it. I have always been able to pass the Ga. emission test up till now. The CO% was too high on the 50/15 test this time. Does anybody know of any tricks that can help me? I've heard that you can put that stuff in your gas tank thats supposed to help or to retard the timing to the point that it will not run.
Also, is there a way to bypass and turn on the exhaust plugs. I had to bypass the A.I.V boxes because the hot one rusted out.


Thanks for your help.
