A friend of mine bought this at a swap meet. It's a 65cc, and he is thinking about a 24" prop for it. We have no idea who the mfg is, nor are there any markings. It has a Walbro carb. Some positive ID would be a big help.

I should add that it is going to fly a big ol stik bipe. 16 or so pounds.

#1- it's definately a Lawn & Garden conversion. #2 How do you know it's 65cc

Yeah it's a conversion from something, note the four wire ignition???

Guys, thanks. He measured the engine, and figured at 65 cc or so. The only thing I can tell you, is that it's timing is adjustable. I haven't seen it run, but the nylon piece on the front rotates about a quarter turn from idle to full throttle.

I can't tell you what it is, but it looks like it could use a few more bellcranks.
Setting the timing and synchronizing the carb will be blast!

I would agree with the conversion, but there are mounting flanges on the crankcase very similar to smaller 2 and 4 strokes. Seems like it was made for model airplanes.
