As I learned just weeks ago from a post here, the hole I think you are seeing is exactly what I see on mine and seems to be normal (plugged of course). Between the air cleaner assembly and the fuel injector hoses at the fuel distributor is a tiny raised ring-looking thing with a hole in the center. This looks like a screw or something should go there, but what you really need to do to adjust your mixture is get a 3mm allen wrench that is at least 100mm long and pop it down in there. I am not sure of the specifics but I turned mine counter-clockwise about .25-.5 full turn to get my emissions to pass. This was after I did a complete tune up which did not help the emissions results at all. See all posts related to idle mixture adjustment screw within the past 2-3 weeks to get some great pictures from other members. --- In dmcnews@xxxxxxxxxxxxxxx, "Tom Tait" <TTait@xxxx> wrote: > > I need to get my tamper proof plug opening clear so I can try to correct > a mixture problem.
