Need help finding carb parts
 

Hey all, I have a Zenoah G270RC that I am running on my goped scooter. I recently came across a remote needle adjuster for it that was made back in the day. The only problem is, when it was made, the 990 carb wasnt being produced. I basically need a T-handle high speed jet for this to work, and I cant find anyone who makes one. Does anyone know of such a beast? Or can I custom make one?
