Received one of these with the motor hanging off the deck attached only by the self-propelling belt and the cables.
The deck had rusted away around the three mounting bolts and it was on its way to the tip. A thick mass of dried grass cuttings was under the deck and on top leaf litter and grunge, no wonder it had rusted.
The motor had good compression and I thought it worth a bit of time and effort. Getting the crankshaft boss off was a hassle. Disconnected the self-propel mechanism, rotated the motor 30 degrees and drilled new mounting holes into the deck, cleaned out the fuel system and now have a nicely running mower, quite powerful.
Anyone wanting the SP drive belt let me know, yours for the cost of postage.
