Thats a Picco, Prather did not make motors.

Thanks that helps a lot. Do you happen to know anything else about it? I've been trying to look it up on google but can't find anything at all. The motor doesn't have any markings except for a 5 printed on it. Other than that I have ran it before and seems to be a high high performance motor. I am also possibly looking to get rid of it if i can't get it to run right but for now any other information is well appreciated. Also does anybody possibly know if there is a direct replacement for it in like an O.S or even what size it is?
Thanks again

Just found that old post while surfing the net;) The engine is a Picco P-5 3.5cc/.21 ci, an excellent engine in its time. An OS .21 would be trading down[:o]

Yup, it sure is! If my rusty memory serves me right, check the head bolts as they could be exposed inside of the cooling jacket and subject to rust. If so, they'll need something like anti-sieze compound on them or you'll never get them off if you need to.
