I'm kicking around the idea of swapping my kohler 321 k 14 horse power motor for a diesel engine. Haven't figured out why my motor won't fire up. My thinking is if I have to drop a few hundred bucks on my old kohler engine, it might just be better to get a new one without spark problems. I was wondering if anyone else has done that swap in a gt14 and open to any thoughts on the subject. It is a working tractor. Or it use to be.
