Help ! Help ! I appreciate all the positive feeback that I have received in support to my question. Even Ken at Cen Racing has helped me quite a bit. After all that, my real conerns are not be answered. Has anyone out there sucessfully installed a NX-15 engine into a fun factor MT2? And if so, can he/she send me a diagram, or even better, a few sample photos of your vehicle. I am stuck with the location of the proper installation of the engine, as well as how to setup the throttle linkage for the slide type carb. My linkage was setup for rotary carb from the factory NX-16 engine. Can anyone assist me out there? Most Appreciated. [&:]
