This is just something I was playing with, and realized it could be used as an engine idler, allowing the engine to run without influencing the drive train. It would need a few more parts to allow the drive wheel to turn the output (yeah..... I couldn't figure that one out). If anyone would help me out a bit, a way to make the system engage/disengage would be extremely appreciated. This will become part of an engine I am making, and I am excited to release that. The whole thing is pretty fragile because the part that connects the piston-like thing (I don't know what its called, but you get the point) to the slider is just a tiny box. Needs work, but if anyone wants to use it, go for it. That assumes that you can find something to use it for.

This is my first upload, so play nice. XD
