I just got my new TT .39 and stuck it my venture. ( pretty!) When I went to start it I could not get it going and I had to give it almost half throttle just to get it to start. The needle was two turns open, the manual says to break it in with the needle three turns open but I could not get it to start at that setting. It makes a lot of smoke and will not idle below about one third throttle. Is this normal?
