I just bought a macstar to put in my ofna mbx buggy.I didn't get anything other than the motor and carb in the box[&o]No setting sheet/nothing.I can't find the factory settings for this motor anywhere online.I was gonna go with the settings off my force 28 but the carb is different has a screw on bottom of the fuel inlet.It fired right up, yesterday was the first try at getting it broke in.It is way fat the way they all came set.I got it to 220 and shut it down at BDC.I haven't tried again becouse i'm lost on what that other screw does and where my needles should be set at for break in.Any info on where they should be and what is the other screw on the inlet.Thanks
