Ok, Here are some pics. Feel free to comment, I haven't read or seen anything about the GX25, so I am curious as to what others think as well. The only "problem" is the carb mount, It doesn't have bolts on each side of the port, it has a plastic tube with an o-ring that fits into the port, and then the screws are much further apart, I guess I'll just trim away most of the plastic, except for the bolt holes and the webbing, but remove the baffles and other excess material. I don't think it will look very good though. Also notice the extra "lever" or "foot" inside the cam gear, that foot rotates another tiny lobe on the cam to hold the exhaust valve open slightly during starting. That is their automatic compression release. Once the engine is running, that foot slings towards the outside, locking the additional lobe in flush with the face of the cam through some tiny linkage.
