will185 \ SpinnerRow - I've noticed the same thing with this DLE 20 - I can't seem to kill it with the throttle control alone. And I've also confirmed that the throttle plate is seating correctly. Must be some other air\fuel leak in there? Does anyone know if this carb is designed this way? Seems odd. But, as Spinnerrow states, I use an Opti-kill swtch or a servo-controlled choke to kill it (depending on the plane). Haven't tried to kill my DLE 30 with throttle control yet - will have to test that next time out.
