In an almost repeat performance of their opening round in Turkey, the Davenport duo shot two-under-par on the front nine with birdies at holes three and seven.
At this stage Clark and Williams had overtaken their rivals on the leaderboard after reaching the same stage on four-under-par. But Howarth and Wilson dug deep, scoring four birdies on the back nine to finish on 86 points, just one point ahead of Caerphilly.
Oakmere Park Golf Club’s Daryl St John-Jones and Thomas Pang (a) finished third with scores of 41 and 43 giving them a final total of 84.
