RE: How warm to the touch does your cowl get?
Jim,
I have the same combo, and have made the same observations. Gotta remember the fuel also cools the glow motors. I understand that these motor run hotter and that warm feeling is normal. I have almost 3 gallons through mine now.
Also, I would wait untill you switch to the "normal" mixture before fooling with the settings too much. My transition is also not the greatest, but it is on the rich side, and I will leave it there untill it is broken in.
Good luck

PS, Can anyone else confirm this?
