An awesome gift and friend: OS FS-40

A member and friend from RCGroups, that would be Kimchiyuk! So I have sold this member a few engines, bought a few from him, and we have corresponded several times. Well I was about to lay in my recliner and take a nap when I here the postal truck deliver the mail. I figure I better get that before I nod off. Out to the mail box I go and when I open it there is a small box! WTH? The engine I just bought from eBay could not be here yet.... What is this? I see the return address and see Dustin's name. I wonder if I made a purchase I did not remember. So I anxiously go into my room and open this package. I find a completely disassembled OS FS-40 four stroke engine! Wholly moley! I love engines, let alone totally disassembled ones! There was this note also.... In summary it stated that Dustin had been working on this engine but lost the desire to complete it. Knowing I am an avid engine lover, he sent it to me. The note went on to say and I quote, "Keep it, sell it....It's yours." I quickly scanned the box and parts and it looked like everything was there. The caveat being the piston pin was still firmly attached to the piston. These can be quite tricky to remove. OS engines require the cylinder sleeve to be pulled out and then a hole in the casting is exposed allowing careful extraction of the piston pin. A task much easier said than done especially if the engine has sat for any time at all, or has not been run in a while. Long story short, it took considerable oil, heat, a soak in LA's Totally Awesome cleaner, more oil, PB Blaster, and more heat. Eventually I was able to start moving the pin back and forth. I knew I had it on the ropes then. Using a 3mm screw I partially screwed it into the pin and carefully pulled it out.

For those that do not know, if you cannot get this pin out of the piston you cannot remove the crankshaft and thus cannot replace the bearings on the engine . Which by the way a new set of Boca Bearings also came with this engine.It really looked like a pretty low time engine. The valves were pretty clean. I did remove them and cleaned a small amount of carbon off the exhaust valve. The piston was extremely clean and the ring was not compressed at all. This engine now looks nearly new and has very good compression. Unfortunately I was so excited and focused on the task at hand I did not shoot any video, and only took a few pictures. I will be shooting video tomorrow when I run this engine for the first time. I have to say THANK YOU very much Dustin. I'm sorry I didn't draw this out longer but it is ready to run the same day it arrived.... My bad....
