Slightly OS but this applies here too I'd imagine. I went to replace the blades on an old Victa lawn mower to find that the bolts - with the nuts on the underside of the flywheel - are well and truly rusted as well as the reverse threaded bolt holding the flywheel to the shaft. I've used a good amount of WD40 over the last week and holding the flywheel in place with a block of wood and helping my wrench with a hammer but still no luck. The local mower repair place wants just to remove the old bolts and blades (I have my own new ones). Any suggestions for someone without a good set of tools? Cheers, Shane.
