Today I took the head off the Beeman to see what I could see. I am no expert, but the cylinder wall looks fine to me and the piston moves as it should. Neither one of the valves moves though (and you can see the exhaust valve is covered with a pretty thick layer of carbon). So, no valves moving, no magneto shaft turning and no fan turning (although as of yet I have no idea exactly how it's driven). I'm thinking perhaps a camshaft issue, given that neither valve is working, nor is the magneto shaft? More exploration needed, clearly. So, I'm thinking that my next step is to take the wheels off as it looks as if there are covers behind the wheel on the side of the block, hopefully to access the cam and what not. I didn't really take a good look at it, to be honest, as time was short. This will be my first time really taking apart an engine like this, so it will be a real learning experience. Please feel free to give me advice on this little guy as I'm very much making this up as I go. While I am mechanically inclined (obviously, or I wouldn't be here), this is new to me, and this engine isn't quite the same as what I'm more used to working on. Obviously, the principles are the same, but some of the particulars are new to me. Anyway, I'm guessing that the flywheels and the drive wheels are going to be bears to remove, but that's my next step. I want to see if I can address how sloppy they are, as I think are fairly sloppy and I'd like to be able to tighten them up somehow. Also, from what I can see in the 10 seconds I looked at it, it looks like it may free up access to the camshaft and what not. Based on what I saw today and my current working theory, I'm going to look into the camshaft next to see what I can see. If anyone has any advice or alternative theories/suggestions, I'm all ears. As much as I love working on this kind of stuff, I prefer to disassemble as little as possible, so as to risk breaking something as little as possible. By the way, this little guy is one solid chunk of cast iron. What a little beast. By the way, does anyone know if Beeman used Ford model T parts? I know the carb is, and I've heard that other parts are too.
