Jetting for Mikuni VM18

Hey quick question. My stock carb on my 1978 Honda express just isn’t working well after cleaning and tuning. My question is if I put a Mikuni vm 18 will work with the stock cylinder. Also what jets would work for stock. Doing research people have said 110-120 range but that is with an upgraded 70cc kit. It has to be lower for stock right?
