Looks like the one I set up...It was new in the box..I took it completely apart and cleaned out the old hardened grease it was assembled with, and surfaced the cases so there would be no leaks..It ran well, but don't remember the prop size..The con rods have removeable caps with no rollers, so don't try to use fuel without at least 18% oil..Regular glow fuel will be fine..Red Max with all castor would be good..It's very smooth with good transition...Probably a 20-10 prop..I have the twin to it here..I'm going to take this one apart and do the same things and then put ignition on it....The pullley on the hub is for a rope to start it with..Not needed, it starts fine......
