I'm back
 

Hello gents, it has been a while since I have been on here. A few years back I had to rid myself of all my Cubs and parts. I was able to keep a "O" frame and trans. I am finally getting around to getting her back together. I am a lil rusty on navigation through the forum. But any help on engine,K???. I have an O engine, just need carb and air filter. Also looking for the name of that 4x4 black box, and full wire harness. I do have the black box and a wire harness. But both look to be a lil rough. I am just a lil outta touch with terms and knowledge at this point. So, I guess the important one first is engine. I believe it is a proper 7 or 8 hp engine for it. So what k model would that be? I am all over the place sorry and thanks in advance.

Welcome back. :beerchug:

The OEM engine for the Cub Cadet Original was a Kohler K161 (7HP). Later the K161 was updated replaced with the Kohler K181 (8HP). So, either engine is acceptable for the Original.

:Huh:

The sunshine is in my crystal ball today!:beerchug:
4"x4" black box is a voltage regulator.
commonly called Delco Ream-me :biggrin2:
