Running Rich

[steve_civic]

hey guys my 1989 ED6 (D15b) civic is running rich coz its blowing black smoke under acceleration and i was wondering how u guys adjusted the mixtures on the dual carb engine. I heard u had to drill some cap to get to the needle valves but not sure. Im in the Footscray area Melbourne, can u guys help out. Any advice is cool. Thanks:)

you can adjust low end mixture with a screw. http://www.honda.co.uk/owner/ConcertoManual/62sk301/6-15.pdf

should be similar to that

There isn't any carbed civic manuals on the honda site. That one I linked you to is a concerto manual. It had very similar carbs to yours. There is an ed manual around I think. have a search for honda service manuals on google.
