Nate,
It takes a LOT to light my fuse these days, and you definitely did not anger me in any way. Sorry if my post seemed condescending I did not mean it like that at all. I was just trying to stress, "don't overlook the iso mounts" since they seem to cause problems for a lot of our quiet line tractors.
I've been reading and looking around on the web about these K series engines since I have that one taken apart right now. If you check this youtube vid you will see the balance gears I am talking about.

He says one of his was broken, I am not sure if it is or if it is just a casting defect but from what I have been reading a lot of guys are taking these gears out of the bigger HP K series like you and I have because they can fail and cause some nasty engine damage.
My 1450 I am running and cutting with will shake hard the last couple revolutions of the engine when you switch the key off now that I think of it. It may just be the nature of the beast with these quiet lines.
Hopefully nothing serious.
