Oh yeah! I personally found the screw to actually be quite sensitive, I once hit the sweet spot with like one tenth of a turn, before screwing it up during an erroneous diagnostic: I'll work my way out through quarters of turns, until it's still a tad rich.Make sure you take it easy on it till you get the a/f mix nailed down. Don't want to see it die before you have some fun.
I've been looking forward to replace the stock carb with a Dell'Orto PHBG 14mm carburetor to let this little engine breathe a little better, NT carbs are the equivalent of a Dell'Orto SHA 12/12, but the PHBG has a much more generous finesse degree in matter of tuning than the SHA and the NT themselves.
If I knew about the length of the carburetor stud interaxis, I'd braze a manifold myself.
