The carb on my Magnum 40 won't close down. It'll go from fully open to about half closed but that's it. This isn't a servo problem. It' seems to be mechanical with the throttle lever. The engine runs fine but can't be idled. BTW, this problem presented itself for the first time about i5 minutes my last flight when I tried to slow down for a landing. No dice! So I had to fly it around for 10 more nervous minutes until it finally ran out of gas and I was able to bring it in for a deadstick landing. I have crashed recently so maybe something got knocked out of whack.

What's up with this?
