It's basically an earlier version of the 250 .As such it has a lot of lugging power but it isn't something that can run with a modern saw.They don't do bad though considering the age .
For a firewooder they'll still get-er-done .A tad heavy but the thing like most McCullochs will run almost forever .Now were it I,I won't dump a bunch of money in it .Maybe a carb kit ,a few parts .
