Lister D Carburettor Air Valve Spring

I haven't recieve it yet. I bought 2 different items separately and asked if possible could you put them together and save on post but I recieved one item Friday, it would make more sense . I should of ordered them together but for whatever reason I didn't. I asked after ordering them to get an email the next day one was already sent. I'll know it future the tax and the post makes items very expensive from England now, so I might have to source parts in Ireland now. Thank you
