No one will be able to tell you that. Every motor and every carb is a little different. Get an assortment of jets and work your way from rich to a tad lean then back. It's much better to run a motor rich than lean. My bets advice is to find where it has the most hp and runs the hardest, then richen it up a bit from there. Then keep a close eye on your plugs to see how she's running. Knowing how to read a spark plug correctly is EVERYTHING to setting this up and not hurting an engine in the process. Then when you think you got it, replace the plugs with new and see how they burn in. Good luck!
