I have this engine that is labeled a K301. It sure sound heafrier that a 12hp. I don't think the ID tag is correct. Is the engine schroud the same on all quiet line Kohlers? Another thing I noticed is that it has 13 fins. Does any other Kohlers have a 13 fin block?? It also has a fuel pump and a different base. Is there a way of ID'ing this engine without tearing it down? I also want to now if a IH Cub Cadet correct pan can be installed? I'm thinking that this engine was used on a commercial aplication with more oil capacity with the taller base and having a fuel pump the gas tank would be remote. Any thoughts???
