hey guys. I have a keep off .21 4 tuned. Replace front ball bearing once and crank shaft once. I have some problems lately and wanted some help.
1. Low is getting rich while accelerating so i lean it out (high is ok). Needs so much leaning in order to work ok ending up having unstable idle and also RPM is not returning to idle normally.
2. Burning a lot of spark plugs lately. i can do 1-2 liters max with a new spark plug.
3. White smoke always when accelerating from idle.
For sure i will use the keep off for racing so i'm going to fix this. At least i will try to. I would appreciate any help and some tips.

You are too rich on bottom it sounds like. So that is prob the reason for popping plugs and unfavorable acceleration and inconsistent performance. You should return the low and high needles to flush and re tune from there. Make sure the engine is already warmed up for 5 minutes or so before re tuning. You need to tune the needles together especially the low and idol needles. They are both affected by each other. When you start changing one of those needles, you have to compensate with the other needle to balance out the change. Then you'll have to change the high needle too to stay in over all balance of the tune. Its trial and error. WISH THEY HAD FUEL INJECTION!!!!!

No such thing as a "how many turns" needle setting ,there are sooo many things that effect the way these engines work its impossible to offer a set needle setting ,hence why novarossi sends the engines out blubbering rich
