Here's the story with this one: I bought it about 10 years ago. I'm pretty sure that the engine is unused, but I believe that I put a new diaphragm and crank seals in it
when I bought it, because I did that with all of my O&R's. I know for sure that the fuel tank and exhaust have never been used. The throttle cable is a nice aftermarket
version. It comes with an original manual and a tattered box, not shown. There are no guarantees that it is turn key, because I have never met an O&R that was! If you 
are interested, please pm me and I will give you the price and shipping cost.
 
 

Here is a video of another one that my son was riding about 5 years ago:
 
 

I have one in excellent condition that I could sell. Will post photos this eve if interested. 

The engine you have is a Type 133 engine made for the military, many of these keep turning up for sale, usually still in the original box never used, unfortunately I haven't found any reliable source of information for what the military used them for, that include the sites that mention Vietnam and the wrong info given on some sites mentioning WW2 (these engines didn't exist then).
 
The Type 133 engine has a tapered power output shaft, which is the wrong type for the bike kit gearbox which uses a clutch that fits the "D" shaped power output shaft.
 
You are most likely to find these kits on eBay if you keep looking on there, in fact there are three available at the moment, some of which have been on eBay for a long time.
 
Orline kit, missing tank, throttle cable & proper exhaust (it may be hard to find these parts), has best offer available;

Orline kit, missing tank and does not spark, a bit expensive but has best offer available;

Chicken Power branded kit with a bike you may not want, you could ask if they will sell the kit without the bike, also has best offer;

It's little more than clever marketing, the kit was originally sold by Orline using the less memorable name of "Bike Motor Kit" in the mid sixties, picture of the box side shown below (not mine).
 

 
A very similar looking kit was also available near the start of the production of the O&R engine in 1961.
 

 
Here is an advert from 1974 for the "Chicken Power" branded auxiliary engine kit, where they explain that it's gives the estimated power of about 650 chickens for your bike.
 

 
And here is the box side of the later "Chicken Power" branded auxiliary engine kit (also not mine).
 

 
And lastly here is an original TV commercial for the "Chicken Power" kit from the mid seventies on youtube;

Because it makes the bike go clucking fast
 

Hi , just joined the forum .
Got this NOS engine , was planning to "make" a orline chicken power engine but i think i will drop the idea as the engine is a "vietnam" type and not the 181 .
Does anyone have any vintage orline kits to sell . BTW below are the pictures of my orline engine.
thanks
