Hi MM,
If you just want the mower to work for another 20 years then as I do with everyone I do and that is modify the carby. Bit of work to set them up I say about 2 hours to get it right. As for the module any Victa module is fine, easiest ones to find are the ones fitted to the earlier powertorque motors or if you can't find one of those you can buy new modules for about $20 on ebay. I assume this mower still has the points condenser setup and the module means you don't need them, just leave them in situ, don't bother removing them
