Thanks all. Yes I mean the air bleed screw vs. low speed needle valve - still a newbie. Found a website that sells the OS 40LA that said that the "factory setting" for the OS 40 LA air bleed screw is two full revolutions and the high speed needle valve is also 2 revolutions. I will try this, start it up and see if that does the trick. There was a lot in the forums on air bleed adjustments that I will try.

As for the eov .46, apparently there were some problems with the setting of the low speed needle from the factory. I will try these settings (1 1/5 out) on the low speed and see if that works as well. The evo has that retaining set screw the needed to be removed before I could adjust the low speed needle, but RC universe forums helped with that instruction as well.
