I've got a 1976 Sears Ted Williams model 7.5HP, same motor just different name. Same as caver on mine too, first or second pull and she's off. BUT just like everything else, you will have good AND bad.
I've owned a 1.2 horse and a 3 horse. Both were air cooled and great little weed eater kickers. They did their job and were easy enough to work on that even I could fix stuff on them. I believe they were made by Tanaka.
