I received a 1985 Honda Ht3813 mower for free from a friend. I know it is liquid cooled, 2 cyclinder, and overhead cam. Its bascially a car motor. Can anyone give me some more info about it, or does anyone own one. How hard are they to work on. I wanted to make a racing mower, but after getting it, it's in way too good of shape to do that to it. I am going to get it running and restore it.
