Someone asked about needle settings... I run my jammin motor on a small indoor track with the weather right now at about 45-60 and med moisture. 4.5 turns out on the bottom and 5 out on the top. I run the ofna hot(picco) plug and at about 35-45 end point on throttle with a 8mm venturi I get 220 degrees and about 7.5 min+ on a 125 associated tank. When you limit the end point of the throttle ive found that it changes your tuning mindset a bit. Bottom end becomes more crucial than if you ran the motoro wide open.
