Even if your compression numbers aren't dead accurate - what you show should be adequate for the motor to run nicely. I don't think you addressed ignition timing in your post. Make sure your advance is working. Depending on the year and motor, the B18/20 specs call for timing to be set at idle or 1500rpm. I set to maximum at a higher rpm to assure full advance - and that it isn't too far advanced if something isn't quite right. I use 32-35 degrees as a max.- Dave
