Narrative: Was practicing my landing approach and was planning to go around. I let the motor idle while I lined up. I was going to be a little short and was lined up directly for a barbed wire fence at about 30 feet AGL. Obviously not good, I went to squeeze the throttle and the trigger was limp. Had to make an instant 90 degree left turn and flared while still in a turn. Landed on me feet! Turns out the throttle cable had just enough slack in it, at idle it was able to vibrate off the carburetor rendering the throttle useless. Turns out people put a compression spring in/on the throttle cable where it hooks to the carburetor. This keeps tension on the cable, even at idle, so it will not pop off the carburetor. Glad I had an out!
