Ok lol let me elaborate on a few things because I am getting the same feed back on the idle thing. I have a switch on my radio and I have 2 idle settings one for landing and one for flying. I have a pretty high idle on the high side, and the Idle has not ever been an issue. The high idle so high in fact that if I taxi around with it and never touch the throttle stick. My low idle is only used for landing and starting the engine. I did not accidentally bump the kill switch on the transmitter and I did not accidentally hit the idle switch. The O.S 160fx is not a gas engine it is a glow engine. Speedracerntrixie I will check the pressure nipple, I think the felt clunks are for gas engine only I am not sure they would work well with glow.
