This 1915 10 HP Mogul was Lyle’s first Mogul engine. The flywheel is 41 inches in diameter with a face of 3-1/2 inches. The engine weighs 3,658 pounds. The silver pipe is the exhaust pipe with the muffler on top. The green pipe is the breather pipe, which brings back warm air from the running engine to make it start and run better.
