Abstract
An engine has a flywheel magneto mounted on one end of a crankshaft. The flywheel magneto rotates together with the crankshaft. A cover member is coupled with an engine body and defines a space together with the engine body. The flywheel magneto is enclosed within the space. The space contains lubricant and/or lubricant mist that can adhere onto the flywheel magneto. The cover member defines first ribs that extend toward the flywheel magneto and that are closed spaced from the flywheel magneto so as to remove lubricant adhered on the flywheel magneto when the flywheel magneto rotates. The cover member also defines second ribs extending toward the flywheel magneto and an lubricant collecting recess formed on an inner surface of the cover member. The second ribs also remove lubricant adhered on the flywheel magneto and guide the lubricant toward the lubricant collecting recess when the flywheel magneto rotates.
