I think I started at 3/4th of a turn out. I can't give you any jetting numbers as of yet though. I did manage to get it jetted properly (I HOPE!), or at least close, but that was a couple years ago actually. It's been torn down since then. I'll try to remember to have a look at the actual jet sizes for you soon.
When I get the engine done, I may go back to the original carbs just for tuning.
P.S. I'd like to have more concrete jetting numbers myself. From someone who has actually used the same carbs as I am. 34mm I know someone has it figured out. I emailed Hansen racing once, and all they would tell me was "you should've bought the carbs from us". Real informative.. :lol:
