Hi grumpy, if you click on the link to pics in the first post of this thread, you will see that without removing the motor, measuring the free end of the output shaft would be nigh to impossible because of the position of the cutter clutch being so close to the engine. If the output shaft of the Tecumseh is stepped down, it will be full contained inside the inner clutch half.
