Hi Brian, striped the carb, i was not to impressed with the state of the bore etc so to eliminate the possibility that the carb might be source of the problem i am taking it to the auto cycle company in Dudley town on Friday they deal in amal carb’ spares and servicing etc they will strip and do whatever is required to get it as new condition. so on return if it cures the starting problem great if not then I think I will fit new cylinder base Viton o rings. unless you can think of something else to try….
