I took this off a ruining D14 tractor but to be honest it did\'nt run too well. I cleaned it up nicely. the rebuild kits are easy to find on for 25 to 30 dollars. a new unit cost hundreds. this is a good find for someone who needs it and knows how to rebuild it. actuality it might just need adjustment and not rebuilding but I cant guarantee this and I really don’t know so I\'m listing it for parts.
