Rotax 582 vibrations

[Robin G]

I have experienced similar conditions with both 582 gray and blue heads on my model 3. Very rough idle below 3,000 rpm, then everything smoothes out. (When I purchased the airplane from the original builder, the altimeter needed to be replaced because it had shaken itself to death from too low an idle setting). Carbs are sync'd and jetting is correct for smooth operation and correct temps in flight. ROTAX mechanic on my field played with the idle adjustments on the carbs and things are smoother, but still kind of rough under 2,800. Personally, I have never known either of my 582s to idle particularly well at lower RPMs. I have only used B boxes with each engine. Depending on the time on the engine, you might want to have somebody look at the gears and shims as excessive vibration over time will definitely loosten thngs up. I would encourage you that you can smooth it out, but it is a process not an event.

For the propeller i tried an other one and same problem i would like to put new engine mount because they are 18 age old...
For the lash i shaked the propeller mount in all directions no suspect movments...

I asked John Mc BEAN to have the mount model but no response
they seem like standard rotax models but i don't know about the straightness there is light medium and strong ones...

Is anyone knows how model are they i will be glad

I have John Mac Bean by phone but he asked me a part number.

I haven't any in the buiding documentation only called E-10
For the bolt and nut i have like ANXX-XXX.

Is any KF2 builder can check his documentation to confirm ?

Thanks

i received my lord engine mount today from KF aircraft.

I cross my finger and hope that will stop my vibrations problems

Put them tomorrow...

I put my engine mounts ...same
I changed the gearbox B for a C model ...same

And one day a guy coming from nowhere said "hey did you see...your muffler is touching your aircraft structure.

I fix it differently with the springs and now all it's ok

So now i've got a B model gearbox to sell if anyone interested PM.

So i'll finally going to fly with that KF...
