I bought this motor new 6 years ago with the intent on putting together my first large scale plane, well that never happened, so its been sitting in its box for some time. Motor has always been stored in a climate controlled room and has never seen gas. Its all original, there is also a aftermarket pitts type muffler. (you will need to supply bolts to work with aftermarket muffler, it never came with any). The carb was just rebuilt(put in new pump and diaphragm) because i swapped carbs with my my other zenoah. I was in a pinch one day that i wanted to fly and my local small engine shop was out of the rebuild kits. Also you will need to get a prop hub, they are available at horizonhobby.com for $24. there is a few different lengths to fit your application.
