Running rich

Last weekend i pulled the head off my 88 prelude (2.0si 4ws) (b20a5 multi port FI) and replaced the head gasket no problems. Since i did this the car is running rich, when i get into the throttle in 1st 2nd or 3rd it blows black smoke out the tailpipe!! I was wondering if there is a way to adjust the air fule mixture on these cars? I have tried reseting the ECU by removing the clock fuse and it goes back to running rich!! And incite will be appreciated!!

Thank You
Troy

get an FSE Adjustable fuel pressure regulator..it fits directly onto your fuel rail and allows you to adjust air/fuel ratio..
but dont adjust it yourself, either get it dyno'd or take it to someone who has an air/fuel meter who knows what the settings should be

If you blew your head gasket (which I assume you did) you may have fouled your O2 sensor.
Do you have any check engine codes?
If you do replace your O2 sensor do not buy a Bosch, it is **** and will not solve your problem. I fought it for about a year, in which time I tried 3 different Bosch's with no improvements.
Summit racing sells NTK and this is what I used ($70 shipped) I have put about 150 miles on it so far with no c.e.l. It has also fixed my rich condition.
