I would at least get an oil analysis, do leak down and compression tests. If computer information is available--very informative.
The hours is not a issue--but storage may be. Was it fogged? Also since carbureted, you have to drain the carburetors if not used for a month or so. If I run it every 2 weeks then I don't drain. Better if you can get non ethanol fuel.
Also Hondas tend to have a bit more corrosion issue than some of the others, so you want to be sure that bolts are free and able to be turned. One Honda I bought apparently had never been flushed, and left in the salt water for at least 6 months out of the year.
I like my Honda 90, but would rather have a post 2006, fuel injected, and larger alternator.
