Steve & Curt;

Here is a bit of info the both of you may want to look at. On my AT-6 Texan, I went with the Sullivan Onboard Glow Driver System and the Du-Bro Kwil-Fill Fueling Valva. Very sweet setup. The sun came out today but the club field is still under a foot of snow, so I went into my backyard and play with this setup. The OS 91 four stroke came to life after 24 flips of the prop. I setup the automatic operation for the glow driver to come on at low throttle. I was shock on how smooth the OS 91 Four Stroke ran with the glow plug on!! Just before half throttle, the glow plug go out and the OS 91 4-Stroke bring on the power. Bring the power back down to low idle, the plug come back on and the engine just tick. Hit the off switch on the system and the engine quit.
Please let me know if you would like to see pictures of my setup and I will post!!
