Royse, Nice paint job. The gear box,slip clutch and complete design, are like a "Dunham" I had. I tore the gear box bottom bearing mount by a couple of errors, that you may want to consider.
1. I put toooo many HP on small HP rating of gearbox.
2. I allowed the slip clutch to set up, by parking it outside, and not checking it for free, each season.
3. I have since used ones with a 1/2 "shear bolt", that I feel are more "instanious" and more protective of weak gearboxes.

4. Only use with your lower HP "N"s or 600
