Thanks fellas for all of the helpful advice. Right now, my 1200 shakes in mid throttle, but runs quiet and smooth in high throttle and is starting to shake in low throttle. I probably should name that cub Kate, after the old song that says, "I Wish I Could Shimmy (and Shake) Like My Sister Kate"..
Since going to solid mounts will just continue something that I am not pleased with already, I think that would be futile. I think I will go with the EPay ones. I never thought to check the oil pan---
Thanks for that suggestion Brian. I do not think I will make the engine cradle mod though, at this time, since I need this cub for mowing and I am not a welder.
johncub7172, my cub dealer went out of business

so now it is a bit more inconvenient for me to get parts. You have a good looking QL there!!
Any more advice is always welcome and definitely appreciated!!!
With much appreciation,
