Cub123, we're in this together. I just shook down the 1650 I picked up, and decided I want to do a full-out upgrade with the cradle mod and replacement of the ISO mounts. I'm going to go with the $28 set on ePay for the softer rubber and maintain the ISO-quality damping that comes from rubber mounts since I have the 16hp K341. Remember, none of these AQS-series Kohlers have internal balance gears, so my vote is to stay with some sort of rubber mount to absorb the rotational inertia, especially with the 14 or 16hp engines. We did a cradle mod, cast iron oil pan replacement, and aftermarket soft rubber ISOs on my buddy's 1450 4 years ago, and he's still a happy customer with a smooth running engine.
We had bought the oil pan and modded cradle from Patton Acres when we did the overhaul, but it appears that the cradles are NLA from there or anywhere else. Definitely check your oil pan motor mount bolt holes for any issues, and get a new pan if you have any doubts. I've read a lot of people have been satisfied with Brian Miller's solid mounts, but I've gotta stay rubber with the big K341.
