Buy some Opti2 2 stroke oil mix 1.8 oz per gallon for a couple hundred miles and then mix about 1.3oz per gallon from there on out.
Thats what I do and all my engines run great.......
On the carb, go to thats dax web site and order an RT Carb and a cable from Duane and put the #70 jet in it to start with and see what you get, these are good little carbs and I have beenrunning one on one of my bikes for a year now with great results.
