I have this old Ohlsson Rice Motor, we do not know what it's intended use is. What model it is etc.
I attached some images of the motor below. It is at least 30 years old in new old stock condition.
Hi thelowbudget ,
Your engine appears to be one of Ohlsson and Rice's utility engines , and maybe not specifically designed for model airplane use . Ohlsson & Rice made many small engines for a variety of purposes , one of which being to motorize a bicycle . The exhaust casting , really the general looks of it , look kinda heavy for any airborne application .
I'll attempt to enclose a shot of the average O&R model airplane engine for example ...
