I can't say whether the anti vibe mount works well or not because my DLE85 is hard mounted on the standoffs / firewall. I did it that way because the older plane the engine is in doesn't have enough room for the special mount and I wanted to see what the vibration level of the engine was anyway for future reference. I have been pleasantly surprised how smooth the engine runs w/o the special mount. While not actually measured the vibration seems on par with a typical 55 - 60 size single cylinder engine which I think is excellent for an 85. Moving the engine to the next airplane, I will continue with the hard mount. By the way, I've always liked this engine very much. Good solid performance on a 26 - 10 prop. The only thing I have ever noted is that it likes to run just a bit rich at low speed to assure reliable transition to full throttle but that is not exclusive to this engine.

It's been a few years since the last post. Any further feedback on the hard mounted DLE85? I'm considering hard mounting it on a warbird. Seems to shake the plane a lot with the soft mount currently.

I'm pretty sure DA sells a plywood mount now. It's been the standard for a few years.
