3M Engines

[Dean Pappas]

Hi,
With the Hyde mount inverted, the engine mounting surface is about 1/2" higher than the center of the hockey-puck. The whole mount moves down the same amount ... so the firewall gets three new mounting holes. I have had no problem with both an FZ a number of two-strokes in the JEKYLL. You need a nose-ring, of course.

Why would you have to drill new hole in the firewall.   The 3M fits just like an O.S. 1.40 to the dimension.  If you use the oring header and already have an engine mounted the header coupler may hit.  This is cured by moving the engine out to the end of the mount beams.  If the engine mount is already set in the plane then a Karl Mueller header willl work.  He makes one for us that fits great and will clear the mount.  His headers are T&A  <VBG> or email me off list for the fix I have and I'll send ou a photo.
