The boss that the crank mates into would screw onto the front of the crankshaft with a right-hand thread. Cranking the engine anti-clockwise would unscrew that boss, not start the engine. Worth mentioning the boss has angled slots to eject the crank when the engine fires up: I once used a rusty crank that stuck in and flailed around at 20 revs a second while I nursed my knuckles. | |

Fortunately, it was only 1.3L engine, so it wasn't a great trial; also fortunately, the engine was freshly rebuilt and had good compression, new plugs, points, wires, and distributor cap, and the carburetor was in good adjustment. There was no fixed crank, like a 1920 Ford; rather, the jack handle served. | |

Fixed paragraph breaks. <Enter> x 2. I have no idea what '---------------' is for.
