At least one Europa had that hose melt and rupture. We are using teflon lined SS hose enclosed in Thermo Shield with no problems in 200 hours. Has anyone got any experience using wrap on the muffler to help the life of this hose? We're a little concerned about the effects of wrapping just one surface of the muffler - would there be stress on the skin of the muffler where the wrap ends? Have similar concerns about wrapping the pipes. Since they need to be unwrapped around the EGT connections and where they group and go into the turbo, does that cause stress?

We still have a "vibration " at cruise rpm that I am trying to chase down on this Paradise we have been working on It went away after a gearbox reshim/respring but now is back. We are just finishing up a different prop installation to see if that helps with the issue (owner wanted to do this,not my idea) I have checked all the cables,swivlenuts ,etc in the carbs but will no another recheck. Sync is spot on. I now have the prop balancer so will check that out on the Warp we are removing.

When do you think you will get in the air? I am starting a Kitfox SS7 next week, so have left the Zenith world. Going with a continental on this one, but would swap it for a Rotax.

The ends should be dip coated with "End Dip" and have a band clamp as per ASTM standards. The fire sleeve not only protects it from fire, but does a pretty fair job of insulating it from radiant heat off things like the muffler. Where you have a coolant line close to something hot or where it might rub take a piece of fire sleeve and cut it down the middle lengthwise and wrap it at the problem location and use either a couple of wire ties or safety wire to hold it in place. -------- Roger Lee Tucson, Az.

Probably worth considering to have dynamic balance, make absolute sure prop blades are tracking and are at same pitch before.
