If you are looking for a used carb at a reduced price for your Moki, I can't help. If you contact Morris Hobbies they are the distributor for Mark Engines and will be able to get a carb for you. Moki engines are no longer distributed in the US although you can find some still available. Mark Engines are the US ( Moki ) and as far as I know, all previous suppliers of Moki parts are referring their customers to Morris Hobbies.
