3M Engines

[Kenneth Blackwell]

He makes both the ARI(A) (nose ring built-in) and a stiffer "A" mount, (no nose ring) for the 2-C. I have seen and used both on 2C engines. I have fitted a 3M to these mounts with absolutely no clearance problems.

Note: the Webra is taller than either OS or 3M and doesn't need the clearance and will work on regular mounts

  Did I mention that Merle makes a 2-c mount that clears the header??

  Dean's suggestion has been misinterpreted.  He ismaking a creative suggestion to flip the mount over and use it upside down.  Dean is saying that if you mount the engine to the bottom of the Hyde mount (turn it 180 degrees from normal) then the Mintor header will clear the puck.   

  This concerns me for several reasons: 
  1. The engine is no longer on the centerline of the puck - I think this will accentuate translation problems.   
  2. This is completely unnecessary if you already are using an OS/Hatori header.  The dimensions are the same.   
  3. This is completely unecessary if you are building your plane and can mount the engine at the very ends of the rails 
  4. Thisis comletely unecessary if you use a Macs or Mueller header, since they don't have O-rings and therefore have dimensions that fit 
  5. This is completely unecessary if you get a custom mount from "mount man" below that fits the Hyde bolt pattern.

  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.
  Dean

  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.
