Several years ago, I purchased a 2-cylinder Novo engine. I was told it was used on an orchard sprayer. It is hopper-cooled. On the brass tag, it has "Model FU 3 × 4 Serial No. 26694." I would like to know the horsepower and when it was made. I would appreciate any information I can get. Charles R. Sly, 27129 275th Ave., Ewing, MO 63440.
