ASP FS 80 A Look Inside

As promised last week, I did open this newly acquired engine up. It was sold to me as a NIB engine but subsequent internal inspection tells a different story. I initially was going to open it up to check for metal shavings from manufacturing and general quality. This is due to this being an early ASP engine made in China. These engine were not known for being of the best quality and I had heard stories of folks finding metal shavings inside new engines. Although I did not find any metal shavings I did discover this engine was not NIB and never seen fuel. I could tell from the exhaust valve. It was a slightly different color on the face and at first I just dismissed that. But after dropping the valves I could see that discoloration going up the stem of the valve. This is clear proof that this engine had been run at least once before, I completely disassembled this engine and pulled the bearings. They did not feel very good and I immediately ordered another set from RCBearings. I did lube them up and work them a bit and they felt much better. I did decide to just re-assemble the engine with these bearings and get a run or two in to see how the engine performs. Once the new bearings arrive I will be installing them. This will also give me the opportunity to test the theory of how many runs this engine really had before I bought it. I cleaned the exhaust valve up to look like new and today I have run the engine 3 times. Those videos to follow. It turns out this video just so happens to be my 300th video on my YouTube channel! The first run videos will follow.
