Had a "fun" flight this morning. I've been tweeking my cooling ducts and decided to take her up for a few laps around the dog patch to see the results. Everything was fine until I decided to land. I reduced throttle to no avail. It just kept the same RPM. A few more laps around and I couldn't figure out what the problem was. Decision time. How do I land? I decided to climb a 1000ft above pattern and see if I can restart the engine after mixture cut off. It works. So back in the pattern, I make a long approach and pull the mixture. Too high and too fast. Full mixture, engine restarts and do a go around. Next time I cut it on base. I'm high, but know I can slip it to the numbers. I come in real fast. No flaps, just hold until touchdown. A few bounces and I'm down and off the runway.
Back at the hanger, I find the bowden cable sleeve had pulled out of the aerocarb bracket. When I pulled full throttle, it worked normally, but when I pushed to idle, the sleeve just moved up and the throttle slide didn't move.

I caught the episode on video.

Nice job getting it down! I know that's not the first time that has happend. Bob Mika had his throttle cable break on final at OSH-in the idle position!

If you have not already considered it, you might try one of these...

It's worked fine for me. I have a Bowden cable on the mixture.

How do you connect the push/pull cable to the aerocarb and throttle quadrant?

Threaded forks and rod ends do the trick.
