Yes they are good units but older. They have not made those for well over 10 years. Unstable engines are almost always a carb issue. Dirt inside it will cause problems. They are also very sensitive to adjustments of the mixture as well as the governor mechanism.....

Like all small engines....if they sit with gas in them and are not used you are going to have problems....It is a very common problem and adding fuel stabilizer is not always going to prevent this issue.

There is no way to say if it is worth buying without seeing it and doing an evaluation of what it may need.

Looks tell a lot but sometimes they don't look all that good but work fine. Sometimes they look good but have serious problems that would be costly to repair.

Get it running.....try to stabilize it....see if it has normal AC output....Go from there...
