Haven't posted in a while, hope everyone is enjoying their summer and getting a lot of flight time. I have been pretty busy but have been able to get in some time most saturdays.

I have a little problem with my Magnum 91 that I hope you can give me some advice on.

I have had the Engine running now for about a year on my UCD. It hasnt seen a lot of air time since I can only fly on weekends and our season isnt very long here. I follow the manual for just about everything, break-in, setting my high and low idle. The motor has run great for me until last weekend when it decided not to turn off anymore. I rechecked my throws, throttle arm and carburator to make sure everything checked out. My carb closes all the way. This week same problem. It actually speeds up when I close the throttle all the way. I cant even get it to idle low.

Even with the carb closed all the way I am getting air in there somehow. I plan on taking the engine off for a better inspection. I figured I would collect as many thoughts as possible about what to check and try while I am troubleshooting the problem. This is my first 4S so any help would be appreciated.
