Patrick, if the piston is not moving it means a failed conrod.
The two likely causes for that are (1) lack of oil, or (2)
over-revving. These were solid motors.
The front wheels are original; the rears are not. The blade
holder is, I believe, a 'universal' replacement - designed to
take a number of manufacturers' blase designs.
Thanks for all that info, Jack. I had noticed the blade carrier with the multi position- boltholes and had come to the same conclusion.
