In a B model, it really doesn't matter which fuel control is installed. If it goes hot when you go to the idle stop, it needs to be written up. Maintenance can adjust it, and it doesn't take that long. The only difference between the two is that with the CECO you can roll the throttle back just a little if it's looking iffy, while with the Bendix if you back it off it kills everything. There is no reason to live with hot starting engines.
