Ok. Im buring really rich and when i start my car from cold sometimes black smoke comes out. It was so bad that last week my car wouldnt start because the spark plugs were coated with carbon. Once clean the car started right up. So i called john hervey and he says to adjust my mixture. But the delema is that i dont have an adjustment screw (allen wrench) and the hole it is sussposed to go down is still sealed from the factory. Now i was reading a pamphlet that i believe was published from the delorean motor center. (its about 10 pages long) about basic delorean maintenece and care, plus what to check if the car wont start. So on one of the pages it says the idle adjustment screw never needs to be adjusted just the idle computer etc that controls everything. So im debating whether or not to drill and adjust or to replace computer (which is expensive and i dont want to do) any opinions/thoughts are appreciated.
