A fellow pilot at the airport called me up. He is cleaning out his hanger and wanted my opinion on an engine he bought new and never used. Its a new 3300 engine, serial number 554. It has never been removed from the shipping crate. In fact, the prop flange is still bolted to the shipping crate so its not been turned since it was shipped from the factory. This is a solid lifter engine with thick finned heads. The exhaust pipes and muffler are different than any of the three engines I have owned. The exhaust pipes seem to collect together into a single pipe on each side before going into the muffler. Nothing missing as near as I can tell. The Bing carburetor is in there. I estimate that the engine is close to 20 years old but I don't know for sure and the owner does not remember exactly when he bought it.

I pulled a spark plug on each cylinder and took some pictures with my scope, which I have uploaded. A link to the pictures is below. Because the engine was not rotated, in cylinders where the piston was at the top of the stroke, the cylinder walls are not visible nor was it possible to articulate the scope 180 degrees to look back at the valves, however the scope has a side-view camera which I used when it seemed helpful.
