Only once did I lose power in our Champ. My wife and I were flying over north New Jersey and power just went down to idle rpm's. Carb heat made no difference, fuel was on, mag switch checked, no change in rpm's.

We had just passed Sussex Airport about 3 miles back so made a quick 180 and landed downwind against traffic, but everybody saw us and we were down safe.

Investigation revealed the heat shroud inside the muffler had broken loose and covered the exhaust pipe causing a lot of back pressure. This is what brought the rpm's down.

Left the Champ there and the local mechanic, Bill Schatt, pulled the mufflers, shipped them out for overhaul and we picked the Champ back up 2 weeks later.

It wasn't as scary as imagined since I had been flying sailplanes for over 10 years at that point and was used to 'gliding' flight. Still, it gave me something else to be wary of.
