You are going to the right spot. I had a similar problem with my dle 30, when doing a blender I would push down elevator and come up on the throttle when the flame out would happen like clockwork. The engine ran fine on the ground good transtion from low to high. Jody told me to richen the low end while other people said to tap and run the breather line inside the fuse, well the low end trick worked no more deadsticks. Jody told me that if you have to run the breather line inside the fuse you have an airflow issue with your cowl.
