All of the running on the plane is with the cowel off and I ran it with a spinner on the stand too. It is quite a bit cooler now then when I ran it on the stand. It was 85-90 and now it is 45-50 degrees.

On the idle screw you just screw it out enough that you can kill the engine with the trim lever correct??? Or do you set it so that at low trim you have the idle and use the choke to kil the engine or some kill switch???

Thanks,
