This is the camshaft on the Howard 8hp motor. The cams look bent but they have that weird shape to work properly with the 90 degree shaft. The magneto runs off the left side of the camshaft and the external oil pump from the right end.
Both the Howard V twins, the eight h.p. and the 12 h.p. like the one above have unusual shaped cams. Their camshafts run at 90 degrees to the crankshaft rather than parallel like Harley V twins. The magneto is coupled to and runs directly off the end of the camshaft.
