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.
Nice piece of work.
May I ask what size of the rubber tube you guys purchased? I am considering build one for my ZDZ40.
thanks.

I found that a 6"x6"x15" tube fit the disks perfectly. Just like cmoulder my disk were just under 4".</p>
If I get the chance this weekend, I'll bench run the Syssa on my mount. I'd like to run it to get the needles set and make the initial set up in the Focus a bit easier. I went ahead and bored through from the front of the mount so that the firewall screws could be installed from the front. A smart man pointed out that I would have basicaly no space behind the box mount and firewall. I hadn't thought that far ahead. Impossible to mount from behind unless you cut through the main firewall. This wasn't really a reasonable option. So now I have blind nuts in the mount box that allows mounting from the front. It will install very slick now. I installed the ball link on the throttle arm to the inside of the motor. This allows the throttle push rod to pass just to the inside of the mount so it will operate with zero binding and little effect from the engine rotating. (Not that it will rotate much.)</p>
