My Zenoah G-20 was flying fine today when I thought I heard it pop them I lost throttle response. The engine will start and idle for about a minute then quit. It will not rev up when it is running though the throttle is openning and the engine sounds like it is starving for fuel. It is getting fuel but not enough for acceleration. It has maybe two gallons of fuel through it and I removed the side plate and made sure the screen was clean. Has anyone had a similar problem?
