Sorry the engine logs are not more interesting.
The engine compressions reflect the auto fuel has never been used in this airplane.
The compression on the number 4 cylinder was more of a luck of the draw on ring gap alignment than indicative of a problem.
At the time of the last annual, the airplane had not been flown much.
Please note that new Slick magnetos, wiring harness, and plugs were installed. These magnetos replaced the original Bendix units. Both Slick magnetos have impulse couplers for very easy starting. Mag checks are a non-event.
Note in a previous annual, during the refurbishment, the entire exhaust system and heat system was removed and entirely refurbished. The logs do not show that the heat muff may be split and removed to completely inspect the exhaust system without removing the exhaust system.
