Dave Brown Vibra Damp T Beam

[ronlock]

OK, I understand the binding problem.  I'd try fixing that with
larger inside diameter tube for the 1/16 rod, or replacing the
steel push rod with a Sullivan inner/outer system.

I agree with the several folks that note a nose ring will help
the situation.  However, Ive had good results with that mount
without a nose ring.

  Inverted I think would be better.  With the cylinder head toward the side, the weight of the engine is borne by the bolts through the isolators.

  When the back of the engine sank pulling the throttle linkage down, it caused a binding friction between the 1/16" steel push rod and the plastic tube.

    Ive used the vibra damp system on beams with an inverted engine,
    which worked fine.   I'm not sure what you mean by a bind in
    the throttle linkage ?    If you mean stalling the throttle servo near 
    the end of it's throw, that needs to be fixed- it causes excessive
    current drain, and will contribute to early servo failure.

      I have this mount on an ENYA 1.2 4 stroke.  The engine is mounted sideways.  My problem is that the engine sags in the mount so that the alignment is lost after it is run.  This caused a bind in the throttle linkage.  Is this a common problem with this mount?  The screws are very tight.

      I would appreciate any advice  from anyone with experience with this mount.

      thanks,
      Jerry
