Flew from a CTAF airport with no issues; normal landing. Stopped to pick up a passenger. Normal engine start; back taxi on 30. Normal takeoff roll. At about 50 feet above the ground; the engine starting surging; from full throttle to idle to full to idle at about 1 second intervals. Changed gas tanks; tried both mags; checked primer lock; all was normal; engine still surging. Had enough altitude to go around about 1/2 the pattern; landed safely about mid field on RWY 30 and taxied back to the ramp.  Taxiing back to the ramp; my right wing tip hit the rudder of a parked PA-28.  I was obviously distracted by my situation; and could have been more careful; or possibly stopped on the runway or just off the runway and shutdown without attempting to taxi back to a parking spot. I would also note that the other aircraft was parked such that his rudder was at the edge of the taxiway; so anyone taxiing by on the taxiway center line would have struck his rudder.
After takeoff a GLST engine began surging so the pilot returned to land and while taxiing to the ramp distracted; his wingtip struck a PA-28 rudder which protruded in the taxiway.
