New question along the same vein: I recently purchased my first aircraft, a 1974 Mooney M20C N7764M, and after gaining some time in the aircraft I’m noticing a hesitation while advancing the throttle at two different stages. Hesitation number one happens right before firewall on take off. RPM’s gain speed, hit the red line and fall back. Is this a feature to prevent over speed or some kind of an issue? Hesitation number two I’m more worried about. It happens when I advance throttle for a go-around or touch-and-go somewhere in the vicinity of 55-60% throttle application. It’s a solid cough and it’s pretty consistent in that phase of flight (low power setting, with airspeed, while advancing throttle). An A&P friend of mine who admits to having most his experience in fuel injected models thinks I may need to overhaul or replace the carb which, as far as I can tell hasn’t been touched in it’s lifespan. Any ideas? Thanks for your help! Sent from my iPhone using Tapatalk
