Okay - so how have you concluded that the car is running too rich? Are the
plugs fouling? Have you verified that the ignition is 100%?
I ask because fouling plugs can occur for reasons other than poor mixture.
Most of us that have hopped up our cars switch out the stock B1AF needles
for needles that are more rich at high RPM (help me out here, B1E??) not
leaner.
Also - make sure that you don't have other problems that look like a
mixture prob (like fuel leaking into the sump).
I'd also double check the carb float level and make 100% sure that the
needle valve isn't getting stuck (open).
