OS FS-70 Surpass Box to the Bench: Volume 3

So in yet another trade, I find myself in possession of an older OS 70 Surpass engine. I bought one of these new in the early 1990's and it was a fine running engine. Then a few years ago I bought a NIB one here for nostalgia reasons alone, and then traded it off. So now I have another. You may ask why I shoot Box to the Bench videos. Typically with used engines I purchase I open them up, inspect and clean them before I attempt to run them. The last few engines I have received I decided to change that up a bit. If the engine feels like it has decent compression and no external damage I will take the chance of running it. This engine arrived in what I would consider good condition. It clearly had been used but it is unknown exactly how old the engine really is or how much run time it has. The fellow I got it from received it on an airplane so the history is unknown. As you can see from the video the engine starts easily and runs quite well. I plan on cleaning the exterior a bit and taking a peek inside just to see what it looks like. At the conclusion of the last run the exhaust nipple came off the muffler so that is going to have to be fixed with a bit of JB Weld.
