Craftsman 5 HP 21 Snow Blower Engine Electric Start OEM Running 536.885210. Complete running engine, including carburetor, electric start assembly with starter, ignition key, and original OEM key set. Engine starts and runs as it should. Pull start handle will need to be attached to rope once installed in a machine. I’m leaving this separated so you can thread the rope up through the snowblower control panel, then install the handle.
