These pictures were what he has on his ad and full size. It's on Craigslist, he bought it on thEbay 2 years ago. He is out of town right now and said he would get me a picture of the engine up close when he returns. I posted the side view picture because of the two switches. That and the muffler I can see in in the cowl make me hope it's gas. It apears to have a "nitro style" round head and rotary valve style carb. But I can't seem to find any engine with that configuration along with the red cyl jug. Could have been painted by the owner???
