Matt and Bob,

Just obtained a custom vibration isolation mount for the Syssa. Actually it was plywood, and balsa yesterday morning. Made mostly from scraps I had laying around. I had to purchase a tube at a mower shop but it was only $11. I did two layers of rubber and it mad a really stiff mount. Instead of end grain balsa, I used 1/4 inch dense balsa sheet and cut the spacers. I put 8 bumper pieces between the disks to stiffen it up at idle. The only thing of concern is that the way I assembled the back plate I will need to watch the length of the firewall bolts. Guys, thanks for the motivation.
