Two goals from corners late in the first half saw Larne go in at the break 2-0 up. The goals were almost carbon copies of each other, defenders Harry Flowers and Albert Watson the goal-scorers with headers from Marty Donnelly corners.
Stephen Murray pulled a goal back from the penalty spot in the 47th minute after Josh Daniels was fouled in the box by Fuad Sule.
Murray then had a great chance to equalise when he was played through by Jordan Jenkins but he dragged his shot across goal wide of the far post.
Johnny McMurray clinched the win for the visitors in the 74th minute as they broke quickly after Jenkins saw a shot blocked and Larne sub Lee Lynch raced down the right before cutting the ball back for McMurray to volley past Jonny Tuffey.
