Could I get some idea of what clearances seem to be adequate from those of you who are already flying?

Luc. Further to Nev's suggestion below I'd suggest using some copper bars as the heat transfer medium. I had used carefully taped cling film when I fitted mine so it came out easily. Of course the powder coating will increase the diameter so you will need some clearance making to get the frame back in and it will also need freshly bedding on the new Redux Flox mix. I also used saddle washers between the finally positioned tube and the bolt heads/nuts.

Danielsen" Subject: Re: Europa-List: Fuel Pressure Indication Thanks to those who supplied me with informations on this subject. To Bud: I'm aware of the additional parts spelled out in the Installations manual, I also have installed a fuel pressure instrument - otherwise i wouldn't have detected my problem (too high fuel pressure)! My issue was the lack of coherence between the installations and operations manuals. (To give the builder an advice of an indicator system which "is nice to have" in one, while the other spells out danger if you experience a condition you would know nothing about - if you did not follow the advice). Now - this is not the airlines (my background), but I'm pretty sure they would detect and correct such a mismatch immediately. This is definitely a safety related issue and should be adressed by Rotax the sooner the better (to ammend the istallations manual to REQUIRE a fuel pressure indications system). As to my problem: I sorted it yesterday. It was of course a pinched hose in there, and it was quite a feat to repair it! Now everything is nice and green again.

Some good old fasioned elbow work and cleaning will free up the rust. Osphor is a brand name of a corrosion inhibitor which will turn the small amount of rust to oxides that are stable, and a hand painting with care with a good primer and paint will relieve you of the work. If it must be done, Nev is right, not a huge deal, I've done it before, just go slow and take your time. Use a Dremel tool and assortment of bits to reduce the volume of Redux down a bit so not as much heat is needed.

The only practical way to soften it is to use heat, preferably from a hot air gun. Be careful not to allow to much heat to get into the surrounding fibre glass. Masking using two or three layers of un resined Bid is quite a good way to achieve this. It is at least a two person job, one heating and one using appropriate percussive force to break each of the four bonds in turn. The first one is the most difficult. I guess there was no need to suggest removing the bolts first. It is not a nice job and I would prefer not to try it at all unless you are really sure it is necessary. In the early days of classic europas we all had to change our U/C frames due to a re design. It was not fun.

I put sheet silicone, held with little stainless strips, around the holes cut for the engine mount. This provides a good seal around the tubes. There was a good deal of trimming with a dremel to get a good fit. I was going to use fire caulk around the seams but ended up putting insulation over the whole thing anyway so I ommited the sealant. Hope this helps.
