I am the owner of 2 oc3 machines. The newest is a loader machine from a member here.
The first needs rings, right after purchase. So, on to look for another. Second is good, cept a carb that needs some work. Has aux. tranny, geared starter, a rebuild per report etc. they should be fun

Looks like you've found a couple of good machines to work on. Welcome to the Cletrac Forum.
