Couldn't find much on the online store that I was looking for, but did manage to find a belt of the right size in a repco clearance list at a store in Victoria. The local Repco store in Belconnen (Canberra) got it up for me ($18.00 including freight) and I now have a drivable, useable mower. A very noisy, drivable useable mower!! The muffler is shot, rusted through on the outside, & I suspect on the inside too. The muffler's a rather weird shaped beast that ataches to the LF side of the motor, then curls up and across the front of the engine before exiting the cowling on the right. Please see the attached file for a picture of this. I suspect it's an MTD part only.
The MTD part number is 751-0263.
Anyone got any idea where I might get one of these?
