Add galvanized extension nipples
Most snow blower engines have a drain plug design that's guaranteed to drip smelly oil all over the machine and floor. Instead of cleaning up the mess every time, modify and extend the drain hole with galvanized nipples and a coupler, elbow and cap. Start by tipping the snow blower on its side (remove the gas first with a turkey baster) so you can attach the nipples and fittings without bathing in leaking crankcase oil. Install a nipple to extend the drain out far enough to attach a 90-degree elbow and then take a downward path (see photo).
