Sounds like a jetting issue to me. 120 would be a little low if you are at or near sea level on a stock motor, but should be plenty to run. Give us a list of your mods and what your elevation is and we should be able to get you very close on your jetting. I see that you are pre-mixing your fuel, do you have the oil block off kit?
The color of the smoke when the right crank seal leaks will depend on the transmission oil used. Most oils make blue smoke when burned. Good point though, you could also have a blown PTO side crank seal and sucking tranny fluid at higher rpms.
Mine will do the same thing sometimes. No tranny fluid lost, jetting is right. I don't know why.... It could be the type of 2stroke oil I'm using (clean burn synthetic for snowmachines), I could have moisture in the pipe, bad gas, who knows........
Anyways.... have you checked your tors? or parking brake? Are you sure your mixing your gas right? Are you mixing gas and oil but still have the oil pump connected with oil in the tank?
