Dave,

What you have is the old K&B Torpedo 40 with a Perry carb. In it's day it was a good, reliable engine and has the power of maybe an OS .32 today. Probably dates to the mid '70's. Here's a couple pics of mine that is for the time being retired. They clean up really nice if you want to display it. Mine is retired simply because it's worn out. I got a wild hair one day and completely disassembled it, chucked a buffing wheel in my mill and spent the next hour cleaning and buffing. Everything was buffed, including the piston, crank and rod - the inside looks like the outside does.

I used to fly it with a muffler (if that is what you could call it) that basically was an extruded rectangular straight exhaust with a spring inside to help create some back pressure. I think was a DuBro Silencer, but not sure as it's been around 35 years since I acquired mine, and it came with the engine. After a while I picked a Kavan strap-on muffler which is what you see in the pictures. It's big problem was the rear half would rotate on occasion and interfere with the radio until I drilled .

Does anybody have a new ring sitting around for a K&B Torpedo 40? I wouldn't mind getting this one running again and hanging it on a Kadet Mk I.
