RE: Ohlsson & Rice Antique Airplane Engine
Hi,
Jim's assessment appears to be correct. I would caution that if you do run it as a glow to be sure to use a fuel with Castor oil as a lubricant. The old O&R will not last long on current fuels. I believe that Fox still makes fuel with 100% castor. Others may as well. Good luck with your find.
