now there is only one problem and that is a VM is the round slide and TM is the flat carbie which is what the RM came with

The 83 RM250 carb is definitely TM38. I have a 83 RM250 carb in my attic if you'd like me to pull it apart and check the jetting for you.

No, you are right and have sent those settings to Hatricks for the carbie, thanks for your help
