Narrative:

I was flying VFR in cavu conditions and had just leveled off at 4;500 ft on a heading of about 335 approximately 8 miles from 5c1. I was briefly going through the level off procedure of setting the throttle and prop and looked up and saw a light twin heading directly toward me. I immediately made a hard bank turn to the right and lost sight of the other aircraft. It is difficult to estimate how close we came because I lost sight but I believe if I hadn't taken evasive action I may have collided with the other aircraft.
