Yeah, XR's Only sells the 2-stroke version. The noticeable difference is that the 2T version has a single throttle cable that pulls directly on the slide like you have, and the 4T version has two cables that turn a pully/linkage thing that moves the slide. And, the 2T version costs a lot less.
There must be some sort of internal differences because they use very different sizes of jets, but I don't know what they are.
