This Loyal Cycle engine was made by Ron Schindele, of AZ, in 2019. Ron built the engine from designs and castings provided by Rowland Mfg. This one runs on gasoline vapor or propane with electronic spark ignition, and it has only three moving parts. The valving is accomplished by ports and bypasses machined into the piston. The engine ran so smooth and slow that he decided to eliminate the governor. Notice, however, he left the governor weight cast onto the flywheel to maintain proper balance.
