I made a small tool...nothing fancy...just a hook device that I keep with the chicken stick. The hole in cowl for the choke is about 1/8" of an inch, and I just hook the choke and can move it easily. I dont leave it in while flipping it. It's that easy, just a small hook. You can even make one out of a cheap little screwdriver so you have a molded handle. I just store it with the chicken-stick, put it in pocket when flying, and away I go, with only very small hole in cowling.
