As it says in the Ebay listing, Wilko, that's a clockwise K2F. For the A10, it needs to be anticlockwise (as viewed at the drive shaft end). To swap direction, the Ebay listing mentions the need to fit a different cam ring. But you'd also need to fit the opposite direction slip ring and contact breaker assembly and to consider whether the positions of the safety gap screws ought to be changed, and whether the housing needed a bit of shaving nearest the crankcase.
