Jim Jones and Mike Barg at the Meyers OTW repair Center in South Carolina can help. You can reach them on the site by searching in the members directory. We’ll all be at the fly in next month in Fredericksburg, TX next month and that would be your very best bet. There are 5 OTWs in planned attendance. As long as your Kinner parts don’t have you grounded you should fly in!
Another person to check with is Steve Freeman. He has owned multiple Kinners. Ours has a Warner, so I’m of no help on that.
