Got an UK spec NC30 (standard) with that horrible mid range flat spot which seems to be getting worse

It dosnt seem to be reving out cleanly now as well so gonna strip and give them a full service. Has anyone tried
RO road needle kit in a UK spec ?? or should I try the washer route ? any tips or hints ?
It has a new vac pipe and tap kit fitted. Was gonna fit new jets, do the float heights etc
Any advice on very welcome

Cheers
Chris
