There are no balance gears in the AQS engine, and the oil dipstick.fill tube are standing upright, rather than at an angle. I believe there could be some complications with the pan, as the 1250 utilizes an engine cradle, rather than a solid mount engine. The wiring is much more simple with the electronic regulator, rather than the electro/mechanical style found on the 149. There is a muffler box on the 1250 that wouldn't be found on the older 149 engine and the exhaust would have to be re-routed.

I am aware of the differences. I will clarify, as I was under the impression that the 1250 didn't run, but I didn't really mean to take a motor from the 149.
Most of the "issues" you listed are not really issues. The main difference is one is a 12hp, and the other a 14. Assuming that you had two 12hp, all but the stator will bolt on. The stator requires a rear housing change. Between a 12 and 14hp there are a lot of similarities. Without spending some time in a parts book, I'm not for certain, but I believe all mentioned parts will interchange.
