0.S. CV-R .18 nitro engine restoration for Traxxas T-Maxx 1.5 2.5

I picked this engine up and eBay for about $115 shipped. These are becoming harder and harder to find. In my opinions this was one of the best small block, side exhaust, rotary carb engines ever made. I would like to also try a Orion Wasp .18. Those are super hard to find. I have a new .12 Orion.
