Please correct me if in error. .875x1.000 bore/stroke, compression ration 6.5:1, approx 1/5 hp at 5200rpm. Hurleman type spark control as opposed to later brown design. recommended prop size of 14 inch diameter by 8 inch pitch.
AMA contests rules cite this engine for models with at least 688 square inches and a minimum weight of 48.1 ounces. Freeflight contest class "c " engine ( this has nothing to do with the c model designation)
