Hi Alan,
Nothing. They're pieces of junk and people treat them like they're the holy grail of mowers. They are prone to coil failure, particularly the rear cylinder and hard to find replacement parts. You basically have to source second hand from wrecks.They were a gimmick in my opinion and I personally don't care for their looks.
Only good thing, if you can get it to run properly, is the 20" wide cut (over the 18" of other Victas in that line up), very smooth running and the large catcher.
I believe they were made for at least five to six years from late 1975 into the early 1980s.
