89 CRX HF fuel milage problems

[bartsan]

I just put a new remanufactured D15B6 long block in my 1989 crx hf. It is the exact same engine that I took out. The old engine was using a lot oil but was still getting about 42 mpg. The new engine I put in is only getting about 32 mpg. These are supposed to get over 50 mpg. It runs good, just not great mileage. I have new wires, plugs, distributer cap and roter button. I timed it accourding to manufactuers specs. Any of you guys have any suggestions?
