If you have an Android phone, there’s an app in the Play store that I have used with success (Disclaimer: i’m still very new).
The app pulls weather data based on your GPS location (or you can manually input it); based on the variables you set (K9 engine generation, track length, etc.) it will output four different setup variations which should get you pretty close to proper running.
NOTE: Some of the parts listed in the setup I found impossible to source, despite them showing up in many internet searches about TM carb setups K93 needle and CD1 jets.
here’s a thread which should help get started:
