Abstract: A cap assembly includes a body and a tether. The body is configured to be fastened to a container for closing an opening in the container. An aperture is formed in the body, and the tether has a fastener, where a portion of the fastener extends through the aperture in the body. A gap is formed between the portion of the fastener and the body that allows for venting of vapors from the container around the portion of the fastener that is extending through the aperture.

Abstract: The present invention provides a four-stroke internal combustion engine having reduced noise emissions. The engine includes a filter element having substantially flat inlet and outlet sides, a first housing portion, and a second housing portion coupled to the first housing portion. The first and second housing portions define an air chamber in which the filter element is supported. The second housing portion includes an interior surface, at least one protrusion to space the inlet side of the filter element from the interior surface, and an air passageway. The outlet of the air passageway is positioned adjacent the interior surface to deliver air to the air chamber between the interior surface and the inlet side of the filter element. A ratio of the volume of the air chamber to the length of the air passageway is between about 5 in2 and about 20 in2.

Abstract: A starter motor construction including a drive shaft and a spline having an external helical thread is disposed concentrically of the shaft and rotates therewith. An internally threaded pinion is engaged with the spline and moves axially outward on rotation of the drive shaft against the force of a biasing spring to effect engagement of the pinion with a ring gear on the flywheel of the engine. A cushioning mechanism is incorporated between the drive shaft and the spline and includes a pair of metal plates, one of which is secured to the drive shaft and the other to the spline. A resilient disc composed of a rubber-like material is bonded to the opposed faces of the plates and is provided with a continuous peripheral groove. The cushioning mechanism acts to absorb radial torque and axial force as the pinion is moved into engagement with the ring gear.
