Hi Joe,
I had issues with one a while ago and needed a sump gasket and bottom seal for one of these. I haven't seen a parts list for them but my local mower shop (Australian mower supply) was fairly helpful and must have had a parts list coz they got the part number(s) and the parts for me.
Another option would be to get the governor assembly off another chonda like a Sanli or similar, or even a honda if you've got one lying around, and swap it over. It's worked for me in the past and the rover/scotty has to be one of the worst designs for a choke/governor setup
Cheers, Theo
